RFC-Compliant Content-Negotiation Class

Announcing availability of this Class: Conteg

[AlexK]

On Aug 7 moon2005 asked is there a HTTP-compliant implementation of If-Modified-Since-, If-Match, If-None-Match, If-Range and so on? [webmasterworld.com] (the thread is now closed, else I would have posted there). He wanted a full- and RFC-Compliant implementation of producing Response headers to client Request headers.

There wasn't. I looked around myself, and could not find any. But needed something like it myself. 8 weeks later it's written and can be found for download [webmasterworld.com].

Here is a snapshot of the Headline content of the Class:

* Conteg.include 
 * 
 * Content-Negotiation for PHP produced web-output 
 * - Request/Response Headers attempt to be RFC-compliant 
 * - Compression is load-balanced by default 
 * - Document-wide multi search/replace available 
 * - Single array-parameter switches negotiation on/off: 
 * 
 * No switches: auto-negotiates Accept-Encoding (compression), User-Agent 
 * Add: 
 * +Modified-date: auto-negotiates If-Modified-Since, If-Unmodified-Since 
 * +Expiry time: auto-sends Expires 
 * +Etag: auto-negotiates If-None-Match, If-Match, If-Range 
 * +Ranges: auto-negotiates Range, If-Range 
 * +Charset: auto-negotiates Accept-Charset 
 * +Language: auto-negotiates Accept-Language 
 * +Media-Type auto-negotiates Accept 
 * 
 * With the appropriate switches, the routine will auto-send the correct 
 * +304 Not Modified, 406 Not Acceptable, 412 Precondition Failed, 416 Requested 
 * +Range Not Satisfiable, 206 Partial content or 200 OK page + full headers.

Will you be submitting it to PHPClasses or some other public repository so more people can benefit?

[AlexK]

Hmm, I take it that you mean http://www.phpclasses.org/. No obvious place to submit and, frankly, all my time is consumed trying to finalise my own site update.

Nice idea, though, and the feedback would be valuable.
