This is a very dodgy quickly whipped together script for a proxy on Apache.

For those times when mod_rewrite and mod_proxy are just not enough, but you can't or don't want to deploy a full reverse proxy, this is for you!

• Reverse proxy with:
• etag's for HTTP caching!
• caching

Very dumb proxy. You will have to clear out the cache folder if you want to see new/updated content.

Great for server migrations, simply place this on the old server while the DNS propagates.

I have put a rather crude rm -rfv inside clear.php. You might want to remove this on a production reployment & protect it with a htpasswd.

Usually for a reverse proxy, I would just use something like nginx or varnish, however, when migrating websites from shared hosting over to dedicated servers, sometimes you will not have access to install these on existing servers.

This was quickly written so sites could be migrated from existing hosts to new hosting servers without any downtime, as long as Apache was installed with htaccess support. (Think, cPanel shared hosting accounts)
