Unset a header from a proxied response

  • 772

I have a proxy configuration under Apache 2.2 which passes all requests for /blog to a host I have no control over.

I want to unset a particular HTTP header (X-Powered-By: PHP) from the proxied response, so that it is not visible to the browser.

I tried this:

ProxyPass /blog http://blog.example.com
ProxyPassReverse /blog http://blog.example.com
Header Always Unset X-Powered-By

And also this variation:

<Location /blog>
    ProxyPass http://blog.example.com
    ProxyPassReverse http://blog.example.com
    Header Always Unset X-Powered-By
</Location>

In both cases, the header is sent through unchanged from the proxy. I also tried Header Always Edit, also no effect.

Interestingly, if I use Header Always Set X-Powered-By Test, the resulting response contains X-Powered-By: Test, PHP - i.e. my value is added before the one from the proxy. I suspect mod_proxy is running "too late" for mod_headers to manipulate the response.

Is there a way to make Header run "later", or some other directive which could manipulate the response after it comes back from the proxy.
