Thanks about proxy_http. I had proxy_ajp, proxy, and proxy_balancer and for the life of me couldn't figure out why it wasn't working :)

Hello! thanks for fielding this. I came across this searching for the “No protocol handler was valid” error. Also note, if this didn’t solve you issue,… make sure your entry is correct:

1	RewriteRule ^/(.*)$ balancer://YOURAPP%{REQUEST_URI} [P,QSA,L]

[...] Not sure what to make of that, Google again came to the rescue with this helpful hint. It seems that by default Debian doesn’t include the proxy_balancer or proxy_http modules. I enabled them, restarted Apache, and everything was running smoothly. [...]

Bigup on the mod_proxy_http thing as well…I was stumped too.

Thanks! I’ve been trawling the internets for an hour trying to figure out that “No protocol handler was valid” error. I didn’t have mod_proxy_http enabled :) Good lookin out!

Cheers!
