Question

Apache, httpd, 2.2 ErrorDocument + reverse proxy issue

Asked by: schoolfusion

We use a custom page for ErrorDocument 404 to look at what was requested and act differently depending on what it was.  It works fine when that page is run on the same machine, but when we call a page that gets reverse proxied back to a different machine, we get no data about what was originally requested.

What is a better solution here?

Your issue is not a very usual one. Are there any alternatives?

Close, they have a similar set up it sounds like, but that isn't our actual problem.  I'll elaborate a bit more.  When apache calls a custom error handler the page it calls gets access to redirect information - in php this is $_SERVER['REDIRECT_URL'] - that contains the URL the client originally requested.  When that custom error page is a page that gets reverse proxied back to another apache server, the redirect information is lost.

There probably isn't an easy fix.  We're looking for a better alternative than installing PHP on our front line apache machines just to handle the custom error page.

As far as I know, there is no fix if it doesn't work it is by design and there's probably nothing that can fix it. I guess your last resort would be to install apache on the front line machines, though this is not an ideal solution, it works and shouldn't take too much more resources.
