free dating website in south africa internet dating in south africa for free

dating site for christian singles in south africa Note that there is a related problem: modifying content-negotiated resources. Here the consensus seems to be simply not to do it. Instead, the origin server should reveal specific URIs of content that is not content-negotiated in the Content-Location response header ([RFC2616], partnersuche usa florida sales), and user agents should use this more specific URI for authoring. Thus, the remainder of this document will focus on resources for which no content negotiation takes place.free online marriage dating sites

dating site for hiv positive singles in south africa Another related question is the usability of the weak entity tags for authoring (see [RFC2616], free online dating gay sites). Although this document focuses on the usage of strong entity tags, it is believed that the changes suggested in this document could be applied to weak entity tags as well.free online virtual dating sim games

singles aus frankfurt User agent developers in turn were happy to get a new "ETag" value, saving a subsequent HEAD request to retrieve the new entity tag.100 free online dating love romance friendship

singles aus frankfurt oder und umgebung However, at some point of time, potentially during a Web Distributed Authoring and Versioning (WebDAV, [RFC2518]) interoperability event, client programmers asked server programmers to always return "ETag" headers upon PUT, never ever to change the entity tag without "good reason", and - by the way - always to guarantee that the server stores the new content octet-by-octet.free online love dating games

dating south africa gauteng From the perspective of client software that wants to treat an HTTP server as a file system replacement, this makes a lot of sense. After all, when one writes to a file one usually expects the file system to store what was written, and not to unexpectedly change the contents.free online dating love service

do online dating sites get you laid However, in general, an HTTP server is not a file system replacement. There may be some that have been designed that way, and some that expose some parts of their namespace that have this quality. But in general, HTTP server implementers have a lot of freedom in how resources are implemented. Indeed, this flexibility is one of the reasons for HTTP's success, allowing it to be used for a wide range of tasks, of which replacing file systems is just one (and not necessarily the most interesting one).free online love dating sites

does online dating get you laid In particular: loveawake free online dating

  • A server may not store a resource as a binary object - in this case, the representation returned in a subsequent GET request may just be similar, but not identical to what was written. Good examples are servers that use HTTP to access XML data ([XCAP]), Calendaring data (schönste frauen osteuropasingle chat deutschland kostenlos[CALDAV][RFC4791]) or newsfeed data ([APP]).
  • A server may change the data being written on purpose, while it is being written. Examples that immediately come to mind are keyword substitution in a source control system, or filters that remove potentially insecure parts out of HTML pages.

free online dating sim games Furthermore: partnervermittlung ukraine quote

  • An "unrelated" method such as WebDAV's PROPPATCH (see [RFC2518], online dating young professionals london) may affect the entity body and therefore the entity tag in an unexpected way, because the server stores some or all of the WebDAV properties inside the entity body (for instance, GPS information inside a JPG image file).

online love dating games As long as servers store the content octet-by-octet, and return exactly what the client wrote, there is no problem at all.online dating young professionals

ausgehtipps für singles in frankfurt Things get more interesting when a server does change the content, such as in the "simple authoring" example given in single chat münchen kostenlos. Here, the server does change the content upon writing to the resource, yet no harm is done, because the final state of the resource on the server does not depend on the client being aware of that.chat singles madrid gratis

weihnachten für singles in frankfurt All of the content rewriting examples mentioned above have this quality: the client can safely continue to edit the entity it sent, because the result of the transformation done by the server will be the same in the end. Formally, if we call the server-side transformation "t", the initial content "c", and the client-side editing steps "e1" and "e2", thenchat single gratis milano

t(e2(e1(c))) = t(e2(t(e1(c))))

kochkurse für singles in frankfurt e.g., it is irrelevant whether the client obtained the current entity body before doing its second edit.

german top 100 single charts juli 2014 Furthermore, some clients need to expose the actual contents to the end user. These clients will have to ensure that they really have the current representation.free online dating france

online dating quiz games Entity bodies (and thus entity tags) changing due to side effects of seemingly unrelated requests are indeed a problem, as demonstrated in free online dating for interracial, and this specification proposes a way to resolve this in free online dating south yorkshire.free online dating west yorkshire

free online dating north yorkshire kostenlos und ohne anmeldung partner finden

ich suche einen mann kostenlos There are several places in the HTTP/1.1 specification ([RFC2616]) mentioning the "ETag" response header.partnerbörse kostenlos für männer

online virtual sim dating games Let us start with the header definition in partnerbörse kostenlos für behinderte:partnervermittlung polen test vergleich

free online virtual dating simulation games The ETag response-header field provides the current value of the entity tag for the requested variant. Sections online dating role playing games, frauen osteuropa kennenlernen and frauen osteuropa vermittlung describe the headers used with entity tags. The entity tag MAY be used for comparison with other entities from the same resource (see Section frauen osteuropa kaufen).partnersuche für russlanddeutsche

online virtual dating simulation games The meaning of a "response-header" in turn is defined in free online dating sites ottawa:free online dating sites botswana

singles uni frankfurt The response-header fields allow the server to pass additional information about the response which cannot be placed in the Status-Line. These header fields give information about the server and about further access to the resource identified by the Request-URI.free online dating simulator game

online dating sites liverpool The "ETag" response header itself is mentioned mainly in the context of cache validation, such as in online dating rpg games. What is missing is a coherent description on how the origin server can notify the user-agent when the entity tag changes as result of a write operation, such as PUT.dating sites south africa afrikaans

singles night frankfurt Indeed, the definition of the 201 Created status code mentions entity tags (best dating sites south africa):dating sites south africa

vertrag mit partnervermittlung A 201 response MAY contain an ETag response header field indicating the current value of the entity tag for the requested variant just created, see Section dating site south africa gauteng.dating sites south africa cape town

online dating simulation games anime The "ETag" response header is mentioned again in the definition of 206 Partial Content (dating sites south africa free) and 304 Not Modified (dating sites south africa johannesburg), but notably missing are statements about other 2xx series status codes that can occur upon a successful PUT operation, such as 200 OK (dating sites south africa durban) and 204 No Content (online dating profile email search).online dating over 40 south africa

online dating sim game anime Summarizing, the specification is a bit vague about what an ETag response header upon a write operation means, but this problem is somewhat mitigated by the precise definition of a response header. A proposal for enhancing [RFC2616] in this regard is made in online dating over 40 uk below.online dating over 40 canada

online dating over 40 australia online dating over 40

speed dating south africa johannesburg While working on the revision of [RFC2518], the IETF WebDAV working group realized that this is a generic problem that needs attention independently of WebDAV. An initial attempt was made with [draft-whitehead-http-etag] in February 2006, but no progress was made since.online dating rich guys

online anime rpg dating games In essence, this makes it impossible to implement an HTTP resource that conforms to both specifications. Due to the differing use cases of XCAP and CalDAV, this may not be a problem in practice, but the disagreement in itself is scary. Publication of these specifications on the standards track will make it much harder for future protocols to deal with this topic in a meaningful way (comments were sent during IETF Last Call for CalDAV, see <single chat kostenlos app>).partnerbörse kostenlos tirol

online dating sites botswana The 'Entity-Transform' entity header provides information about whether a transformation has been applied to an entity body.dating group south africa

free online dating top sites When used in an HTTP request, its meaning is undefined. In an HTTP response, it provides information whether the server has applied a transformation when the entity was stored last.dating in south africa cape town

single frauen in frankfurt oder In general, entity headers may be stored in intermediates. The main use of this header however applies to the HTTP PUT method, of which by default the results are not cacheable (see [RFC2616], online dating games rpg). In addition, the value format is defined so that a client can reliably detect whether the information is fresh.speed dating games online

singles in frankfurt oder Format:

Entity-Transform = "Entity-Transform" ":" entity-transform-spec
entity-transform-spec = entity-transform-keyword SP entity-tag
entity-transform-keyword = "identity" | "unspecified"| token

entity-tag = <entity-tag: defined in [RFC2616], speed dating 2 game free online>
token = <token: defined in [RFC2616], online dating game anime>

wo kann man kostenlos einen partner finden The entity-tag specifies the entity body to which this information applies.play free online anime dating games

american singles in frankfurt germany An entity-transform-keyword of "identity" specifies that the origin server has stored the entity octet-by-octet, thus the user agent MAY use a local copy of the entity body with the given entity-tag for subsequent requests that rely on octet-by-octet identity (such as a PUT with "Range" request header).free online dating games like my candy love

singles in frankfurt germany Both the absence of this response header and any entity-transform-keyword value other than "identity" specify that the origin server may have transformed the entity before storage, thus a subsequent retrieval will not necessarily return an exact copy of the submitted entity.free online dating games for guys

free online dating games to play schweizer single chat kostenlos

online marriage dating sites Content was stored octet-by-octet:

best online dating young professionals Response containing a stale "Entity-Transform" header:

HTTP/1.1 200 OK
ETag: "3"
Entity-Transform: unspecified "2"

single frauen aus schweiz Note that in this case the newly assigned entity tag and the entity tag returned in "Entity-Transform" do not match, thus the client is aware that the header value is stale and can't be used.

online flirting chat rooms online flirting chat sites

seriöser chat ohne anmeldung The clarification of [RFC2616] (see online flirt chat rooms free) makes it clear that user agents can use "ETag" headers obtained in write operations, as long as they do not require octet-by-octet identity. In particular, a new entity tag can be returned for any method, such as a WebDAV PROPPATCH (see [RFC2518], online flirt chat rooms). This helps dealing with the problem described in partner finden online kostenlos. See internet dating south africa gauteng for details.dating sites in south africa gauteng

free live dating sites The addition of the "Entity-Transform" header (see speed dating in gauteng south africa) enables origin servers to signal that they stored an exact copy of the content, thus allowing clients not to refetch the content. Note that by default (in absence of the response header), a client can not make any assumptions about the server's behavior in this regard. Thus clients will only benefit from new servers explicitly setting the new header.dating site for single parents in south africa
