I need mod_headers
to force download of a file depending on GET parameter.
<FilesMatch "*.gif">
<If "%{QUERY_STRING} =~ /dl/">
#Download header
Header set Content-Disposition "attachment"
</If>
</FilesMatch>
Code above produces an error 500. However, if I wrap it properly in <IfModule>
, it does not do anything at all:
<IfModule mod_headers>
<FilesMatch "*.gif">
<If "%{QUERY_STRING} =~ /dl/">
Header set Content-Disposition "attachment"
</If>
</FilesMatch>
</IfModule>
This makes me think that mod_headers
didn't load at all. But I have it enabled in httpd.conf
:
...
LoadModule filter_module modules/mod_filter.so
LoadModule headers_module modules/mod_headers.so
#
LoadModule heartbeat_module modules/mod_heartbeat.so
...
Is there any debug log to find out what mods have been loaded and what not?
You need to check for the mod_headers.c
module:
<IfModule mod_headers.c>
(See this answer about the .so/.c stuff)
But the reason you're getting the 500 error is twofold.
First, the <FilesMatch>
container expects a regular expression, and "*.gif" isn't a valid regular expression. You probably just want to use the <Files>
container.
Second, the <If>
isn't available in apache 2.2, only version 2.4. If you aren't using apache 2.4, then you're not going to be able to use the <If>
container.
