Disable caching of errors when using Apache as a proxy

Question

When you having Apache proxying (using either ProxyPass or RewriteRule), if the destination returns an error (500 series status) then Apache won't proxy any more requests for 30 seconds. I know there's a way to disable this by setting that value to 0 seconds, but I can't remember how. I think it involves a semicolon and some options but I can't seem to find that detail at apache.org.

When doing development, you definitely want this value to be 0, so you can fix the error and reload the page immediately.

Answer 1

You should use a setting like this; source apache docs

ProxyPass /mirror/foo/ http://backend.example.com/ retry=0
