I talked to Yngve and he has confirmed that it works fine with the latest development-version. Previous Comments: ------------------------------------------------------------------------ [2001-11-09 14:48:26] [EMAIL PROTECTED] No feedback. Reopening. ------------------------------------------------------------------------ [2001-10-02 18:56:00] [EMAIL PROTECTED] So is this problem still valid or not? ------------------------------------------------------------------------ [2001-08-23 22:33:31] [EMAIL PROTECTED] I don't think that it's fixed the way yngve expects: ob_get_length() is still not fixed as far as I know. However, a work-around involving sending a Content-Length header form the ob_gzhandler, has been committed to CVS. See also discussion at http://groups.google.com/groups?th=20970c04f298469f,2 http://groups.google.com/groups?th=723d03bc0ba6cbe5,8 ------------------------------------------------------------------------ [2001-08-22 01:25:40] [EMAIL PROTECTED] this should be fixed in CVS. Could you please try the latest snapshot to verify: http://snaps.php.net/ --Jani ------------------------------------------------------------------------ [2001-08-21 14:43:56] [EMAIL PROTECTED] I am a developer at Opera Software, in charge of the HTTP protocol support in the Opera Browser. We recently received a report of a problem on http://www.amdforums.com . When I investigating this report I found that the problem was caused by an incorrect Content-Length header in combination with a Content-Encoding: gzip header. The length indicated by the Content-Length is actually the length of the original, uncompressed body, but it should have been the length of the compressed body (References: RFC 2616 section 4.4, 7.2 and 14.13). The mismatch between the indicated Content-Length and the actual amount of received data causes Opera to do repeated load attempts (This is a fallback primarily used to handle problems with pipelining and persistent connections). This mismatch also destroys the pipelining and persistent connection capabilities in HTTP 1.1. I actually observed one example where the HTTP header of the next (pipelined) request was received and added to the content of the gzipped file. Investigating the PHP sourcecode I found that the code to add the Content-Length header was disabled. I am still investigating workarounds that will handle this problem, but unless it is removed on the server side it will affect all Opera versions after v4.0, as well as any other HTTP useragent that uses HTTP pipelining and therefore have to trust the Content-Length headers To fix this problem you will have to replace the Content-Length header with a proper header, or remove it. An alternative (for HTTP 1.1 clients) is to use the chunked transfer encoding. This is an example session: GET / HTTP/1.1 User-Agent Mozilla/3.0 (Windows 2000; U) Opera 5.50 [en] Host www.amdforums.com Accept text/html, image/png, image/jpeg, image/gif, image/x-xbitmap, */* Accept-Language en Accept-Charset iso-8859-1,*,utf-8 Accept-Encoding deflate, gzip, x-gzip, identity, *;q=0 Connection Keep-Alive, TE TE deflate, gzip, chunked, identity, trailers (Cookie header removed) with the following response from the server HTTP/1.1 200 OK Date Mon, 13 Aug 2001 175609 GMT Server Apache/1.3.19 (Unix) (Red-Hat/Linux) PHP/4.0.6 mod_perl/1.24_01 X-Powered-By PHP/4.0.6 Content-Length 60928 Content-Encoding gzip Vary Accept-Encoding Keep-Alive timeout=15, max=100 Connection Keep-Alive Content-Type text/html followed by an entity body of 9562 bytes of gzipped data. The gzipped data expands to 60928 bytes of data, as specified in the content length header. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12884&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
