Not enough information was provided for us to be able to handle this bug. Please re-read the instructions at http://bugs.php.net/how-to-report.php If you can provide more information, feel free to add it to this bug and change the status back to "Open". Thank you for your interest in PEAR. I cannot reproduce this with PHP 5RC3 on Win2k. Did you use latest version of HTTP and HTTP_Header?

Not sure what else you need. Code is sample code supposed create caching headers to lessen HTTP server load. Server is Apache2 on localhost, Browser is IE6. After loading the page, then clicking 'reload' the issue appears. The problem only appears with direct connection, when going why proxy it doesn't happen.

The error only happens the second time. Headers sent by IE first time are: GET /caching.php HTTP/1.1 Accept: */* Accept-Language: en-us,de;q=0.5 Accept-Encoding: gzip, deflate If-Modified-Since: 2004年8月05日 12:57:27 GMT; length=0 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Host: supportweb.dyndns.org Connection: Keep-Alive Cookie: ZDEDebuggerPresent=php,phtml,php3 Answer: HTTP/1.0 200 OK Date: 2004年8月05日 12:57:27 GMT Server: Apache/2.0.50 (Win32) mod_ssl/2.0.50 OpenSSL/0.9.7d PHP/5.0.0 X-Powered-By: PHP/5.0.0 Set-Cookie: ZDEDebuggerPresent=php,phtml,php3 pragma: cache, no-cache cache-control: public, no-store, no-cache, must-revalidate, post-check=0, pre-check=0 last-modified: Thursday, 05-Aug-04 12:57:27 GMT Content-Encoding: gzip Content-Length: 20 Connection: close Content-Type: text/html; charset=ISO-8859-1 Headers send by IE second time are: GET /caching.php HTTP/1.1 Accept: */* Accept-Language: en-us,de;q=0.5 Accept-Encoding: gzip, deflate If-Modified-Since: 2004年8月05日 12:57:27 GMT; length=0 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Host: supportweb.dyndns.org Connection: Keep-Alive Cookie: ZDEDebuggerPresent=php,phtml,php3 Answer: HTTP/1.0 200 OK Date: 2004年8月05日 12:57:29 GMT Server: Apache/2.0.50 (Win32) mod_ssl/2.0.50 OpenSSL/0.9.7d PHP/5.0.0 X-Powered-By: PHP/5.0.0 Set-Cookie: ZDEDebuggerPresent=php,phtml,php3 Content-Encoding: gzip Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-Length: 197 Connection: close Content-Type: text/html; charset=ISO-8859-1

Ahhhh... I already see the evil piece: If-Modified-Since: 2004年8月05日 12:57:27 GMT; length=0 I'll fix it ASAP! Thanks a lot for the report, Mike

Thank you for your bug report. This issue has been fixed in the latest released version of the package, which you can download at http://pear.php.net/get/HTTP_Header Note: Bug was in HTTP_Header.
