Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

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

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/*?


mime_module contains the following line:

application/x-msdownload            exe dll com bat msi

The application being proxied accepts PUT /proxy/rest/email@gmail.com and returns 200 OK without setting Content-Type or a response body. According to http://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-24#section- 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.

What exactly are you trying to stop mod_mime from doing? It does several different kinds of processing such as setting handlers for file types and setting the Content-type: header if the application that you're proxying is too broke to do it itself. –  DerfK Oct 8 '13 at 21:17
@DerfK I've added an explanation. –  Gili Oct 8 '13 at 21:33

I can think of three ways to achieve this.

  1. Within a directory, virtualhost or .htaccess context, you can use

    RemoveType .com

    to 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.

  2. 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.

  3. If all data in that directory or location always have the same type, you can set a ForceType for the entire directory/location:


<Location /proxy>
   ForceType image/gif

Is there a way for me to invoke TypesConfig against a specific directory (versus adding types one at a time)? –  Gili Oct 16 '13 at 21:33
Not that I can think of immediately. But given your situation, mod_mime_magic might be more useful - I'll amend my answer. –  Jenny D Oct 17 '13 at 6:32
I tried ForceType none in the sub-directory. Unfortunately this did not remove mod_mime mapping. –  Gili Oct 17 '13 at 18:30
Thanks for your help. I've awarded you the bounty and have posted a separate answer explaining what I did. –  Gili Oct 17 '13 at 18:33
I'm glad you found a solution that worked. This is really a bit of an edge case; I've been doing apache sysadminning for about a decade now and never come across this question before. (Which, of course, is what made it fun to research!) –  Jenny D Oct 18 '13 at 6:55

I ended up doing the following:


<Location /proxy>
    Include conf/remove_mime.conf
