How to set different mod_mime rules for reverse proxy?
By default, httpd contains the following configuration:
<IfModule mime_module>
#
# TypesConfig points to the file containing the list of mappings from
# filename extension to MIME-type.
#
TypesConfig conf/mime.types
...
</IfModule>
This file contains a mapping from filename extensions to MIME types. Normally this is what I want, but I'd like to disable mapping for reverse proxies. How can I instruct mime_module to process /* but exclude /proxy/*?
Why?
mime_module contains the following line:
application/x-msdownload exe dll com bat msi
The application being proxied accepts PUT /proxy/rest/[email protected] and returns 200 OK without setting Content-Type or a response body. According to https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-p2-semantics-24#section-3.1.1.5 this is perfectly legal (since there is no response body).
mime_module thinks the URL applies to a .com file and mistakenly applies Content-Type: application/x-msdownload. Since I know that /proxy/rest/ never returns files, I'd like to disable mime_module for that path.
Solution 1:
I can think of three ways to achieve this.
-
Within a directory, virtualhost or .htaccess context, you can use
RemoveType .comto remove the mapping. I'm not certain whether it will work within a proxy context as that's not an actual directory. But if it doesn't, you could go the opposite route of removing .com from the general list, and then specifically adding it for those directories where it's wanted.
-
However, in your situation it might be more useful to have a look at mod_mime_magic. What it basically does is that instead of having an extension-to-type mapping, it actually looks at the contents of the file to see what it really is.
The downside is that it does increase processing, so your performance will take a small hit. If you're at all close to your limits, you'll want to do some performance testing/load testing first.
If all data in that directory or location always have the same type, you can set a
ForceTypefor the entire directory/location:
.
<Location /proxy>
ForceType image/gif
</Location>
Solution 2:
I ended up doing the following:
httpd.conf:
<Location /proxy>
Include conf/remove_mime.conf
</Location>
