Bug #17098 Updated: apache sending 304 - not modified header

ID: 17098 Updated by: daniel.eckl@gmx.de Reported By: pmoor@netpeople.ch Status: Open Bug Type: Apache2 related Operating System: custom linux PHP Version: 4.0CVS-2002-05-08 New Comment: I'd like to post a workaround without patching apache or PHP.... Just edit your script(s) to send a 'header("Last-Modified: Mon, 26 Jul 1997 05:00:00 GMT");' or just some other date older than the mdate of your script file. This solves the problem. Reason: The bug causes Apache2 to look for the mdate of the .php file to determine if it has been modified. If the browser first gets a header like above, it next time asks for the page with an 'If-Modified-Since: Mon, 26 Jul 1997 05:00:00 GMT'. Then, the httpd looks at the mdate of your script, which is always newer and says: Yes, it has been modified, "200 OK". The script will be served and it will response again with the header line from above. Round and round the story goes. :)) Greets, and have fun!

You can have a quick workaround for the moment - just comment out the If-Modified-Since handling stuff in Apache2: Comment out line 393 in modules/http/http_protocol.c, (return HTTP_NOT_MODIFIED). Now, Apache2 does never return 304 Not modified. And hey, this is a preliminary hot fix only! Please also check the suggestions of Justin Erenkrantz (see Apache bug report), I haven't had the time yet to do so. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
