[ mod_headers cannot modify existing headers ] In case anyone comes across the same problem, I have not found a solution. I have run the simple tests below on a xampp-dsl virtual machine, and they work exactly as I expect they should, leading me to believe that there is something fundamentaly wrong with httpd 2.2.2 installed on fedora core 5.
I will simply be scrapping fc5 and installing f7, hoping that this is a bug exclusive to httpd v 2.2.2 / fc5. ----- Original Message ----- From: Neil Simons To: users@httpd.apache.org Sent: Monday, April 07, 2008 5:51 PM Subject: [EMAIL PROTECTED] mod_headers bug? Has anyone had experiences where mod_headers directives often fail to have any effect? - It is unable to modify headers, only create & modify newly added headers. Within my .htaccess file I carried out the following simple tests. 1) Header always set MyCustomHeader myCustomValue -- this works fine Header always set MyCustomHeader2 unsetMe Header always unset MycustomHeader2 -- works as expected - the header is not in the response 2) Header always set Cache-Control max-age=33 -- this works ONLY if apache doesnt normally include a Cach-Control header of its own accord. 3) Header always set Cache-Control max-age=33 Header always unset Cache-Control -- as with 2), this works ONLY if apache hasnt already added such a header It seems that mod_headers cannot operate on *existing* headers! - Only on headers generated by itself! I have searched through various bug lists, archives, documentation etc.. but to no avail. NB, I have used the 'always' condition keyword to ensure all header tables are used. Without this keyword, the tet results are the same. Environment: Linux, Fedora Core 5 httpd 2.2.2 Regards, Neil Simons
