The HTTP / 1. 1 header specification for a HTML document must label an appropriate encoding in the Content-Type header, missing < tt > charset =</ tt > parameter results in acceptance of ISO-8859-1 ( so HTTP / 1. 1 formally does not offer such option as an unspecified character encoding ), and this specification supersedes all HTML ( or XHTML ) meta element ones.

Due to widespread and persistent ignorance of HTTP < tt > charset =</ tt > over the Internet ( at its server side ), WWW Consortium disappointed in HTTP / 1. 1 ’ s strict approach and encourages browser developers to use some fixes in violation of RFC 2616.

The " Content-Encoding "/" Accept-Encoding " and " Transfer-Encoding "/" TE " headers in HTTP / 1. 1 allow clients to optionally receive compressed HTTP responses and ( less commonly ) to send compressed requests.

The specification for HTTP / 1. 1 ( RFC 2616 ) specifies three compression methods: " gzip " ( RFC 1952 ; the content wrapped in a gzip stream ), " deflate " ( RFC 1950 ; the content wrapped in a zlib-formatted stream ), and " compress " ( explained in RFC 2616 section 3. 5 as ' The encoding format produced by the common UNIX file compression program " compress ".

The standards development of HTTP was coordinated by the Internet Engineering Task Force ( IETF ) and the World Wide Web Consortium ( W3C ), culminating in the publication of a series of Requests for Comments ( RFCs ), most notably RFC 2616 ( June 1999 ), which defines HTTP / 1. 1, the version of HTTP in common use.

HTTP / 1. 1 is a revision of the original HTTP ( HTTP / 1. 0 ).

In HTTP / 1. 0 a separate connection to the same server is made for every resource request.

HTTP / 1. 1 can reuse a connection multiple times to download images, scripts, stylesheets et cetera after the page has been delivered.

HTTP / 1. 1 communications therefore experience less latency as the establishment of TCP connections presents considerable overhead.

The HTTP WG planned to publish new standards in December 1995 and the support for pre-standard HTTP / 1. 1 based on the then developing RFC 2068 ( called HTTP-NG ) was rapidly adopted by the major browser developers in early 1996.

By March 1996, pre-standard HTTP / 1. 1 was supported in Arena, Netscape 2. 0, Netscape Navigator Gold 2. 01, Mosaic 2. 7, Lynx 2. 5, and in Internet Explorer 2. 0.

That same web hosting company reported that by June 1996, 65 % of all browsers accessing their servers were HTTP / 1. 1 compliant.

The Apache Software Foundation ( ASF ) is a non-profit corporation ( classified as 501 ( c )( 3 ) in the United States ) to support Apache software projects, including the Apache HTTP Server.

Software standard organizations like the W3C, IETF develop software standards so that most software can interoperate through standards such as XML, HTML, HTTP or FTP.

This method gives the HTTP server a convenient way to alter document's encoding according to content negotiation ; certain HTTP server software can do it, for example Apache with the module mod_charset_lite.

< tt >< meta http-equiv =" Content-Type "></ tt > may be interpreted directly by a browser, like an ordinary HTML tag, or it may be used by the HTTP server to generate corresponding headers when it serves the document.

Many business applications being written today use the client – server model, as do the Internet's main application protocols, such as HTTP, SMTP, Telnet, and DNS.

Both support FTP and HTTP and can work through firewalls and proxies.

For HTTP access the application gateway is called a web-proxy or just a proxy.

The two techniques can be used together with the packet filter monitoring a link until it sees an HTTP connection starting to an IP address that has content that needs filtering.

In the case of HTTP PUT or POSTs, the user-submitted data is provided to the program via the standard input.

While Freenet provides an HTTP interface for browsing freesites, it is not a proxy for the World Wide Web ; Freenet can only be used to access content that has been previously inserted into the Freenet network.

The Freenet file sharing network stores documents and allows them to be retrieved later by an associated key, as is now possible with protocols such as HTTP.

Internet Security Systems was widely criticized for allowing less than eight hours before disclosing details of a vulnerability in the Apache HTTP Server.

The client connects to one of these push proxies using a HTTP request and the proxy sends a push request to leaf on behalf of the client.

File transfers are handled using HTTP.

RFC 1945 officially introduced and recognized HTTP V1. 0 in 1996.

The HTTP / 1. 0 specification defined the GET, POST and HEAD methods and the HTTP / 1. 1 specification added 5 new methods: OPTIONS, PUT, DELETE, TRACE and CONNECT.

In HTTP / 0. 9 and 1. 0, the connection is closed after a single request / response pair.

Version 1. 1 of the protocol also made bandwidth optimization improvements to HTTP / 1. 0.

A request line containing only the path name is accepted by servers to maintain compatibility with HTTP clients before the HTTP / 1. 0 specification in RFC 1945.

Originally defined as part of HTML 4. 0, it is most commonly used for submitting files via HTTP.

IP-address overloading is possible through a feature in the HTTP version 1. 1 protocol, but not in the HTTP version 1. 0 protocol, which requires that a request identify the domain name being referred for connection.

WSDL version 2. 0 offers support for binding to all the HTTP request methods ( not only GET and POST as in version 1. 1 ) so it enables a better implementation of RESTful web services.

KHTML was preceded by an earlier engine called khtmlw or the KDE HTML Widget, developed by Torben Weis and Martin Jones, which implemented support for HTML 3. 2, HTTP 1. 0, and HTML frames, but not the W3C DOM, CSS, or scripting.

:% u0003 % u8b00 % u531b % u53ff % u0078 % u0000 % u00 = a HTTP / 1. 0

IIS 6. 0 also contained a new kernel HTTP stack () with a stricter HTTP request parser and response cache for both static and dynamic content.

* MIDP 1. 0 requires only HTTP support.

SSL is especially suited for HTTP since it can provide some protection even if only one side of the communication is authenticated.

* The domain name portion of a URL is not case sensitive since DNS ignores case: < tt >< nowiki > http :// en. example. org /</ nowiki ></ tt > and < tt >< nowiki > HTTP :// EN. EXAMPLE. ORG /</ nowiki ></ tt > both open the same page.

Intercepting also creates problems for HTTP authentication, especially connection-oriented authentication such as NTLM, since the client browser believes it is talking to a server rather than a proxy.

Finally intercepting connections can cause problems for HTTP caches, since some requests and responses become uncacheble by a shared cache.

Often they use an HTTP service request since even restrictive environments usually allow HTTP service.

As with many other HTTP request headers, the information in the " User-Agent " string contributes to the information that the client sends to the server, since the string can vary considerably from user to user.

However, this transport layer session mechanism should not be confused with a so-called HTTP session, since it does not last a sufficiently long time, and does not provide application level interactive services such as dynamic web pages.

* Supports HTTP, HTTPS, FTP, Microsoft Media Services, RTSP, BitTorrent and since version 1. 8. 4 eDonkey downloads

The only non-controversial counter-argument to using clean URLs is that they would be leaked in the HTTP referrer header field when a user clicks on an external link from a post, which is undesirable for private ( sub ) forums, since a URL derived from the topic title could convey sensitive information.

Alternatively, an HTTP route is available for clients behind a well-secured firewall, with HTTP requests being used to upload messages from the client, while downloading all messages which have accumulated on the server since the last request.

The oldest PURL HTTP resolver has been operated by OCLC since 1995 and can be reached as < tt > purl. oclc. org </ tt > as well as < tt > purl. org </ tt >, < tt > purl. net </ tt >, and < tt > purl. com </ tt >.

It is difficult to be precise about " dynamic web page beginnings " or chronology, because the precise concept makes sense only after the " widespread development of web pages ": HTTP has been in use since 1990, HTML, as standard, since 1996.

Unfortunately, proxies require the user to place a large amount of trust in the proxy operator ( since they see everything the user does over HTTP ), and may be subject to traffic analysis.
