I followed the tutorial from Coda Hale[1] on setting up Mongrel/Mongrel\_cluster and Apache to move away from my current Apache+FastCGI setup. The mongrels are all working fine, and Apache is proxying all dynamic requests through to the cluster using proxy balance. Strange thing is now, that all my images in public/images aren’t loading at all, if I access them directly I just get a URL link to them in the browser window. The Apache logs seem to indicate that the image is http 200 and served to my browser, I am able to access other static files, such as css, and it is served correctly by Apache. If I type in an incorrect image URL then Apache correctly gives me a 404, so looks like it is finding the file, but just not sending it to me correclty. I’ve used curl to check that mongrel is serving the dynamic stuff, and apache the static stuff and this is all correct. Just the images are causing a problem. Anyone else experienced something like this when setting up mod\_proxy\_balancer?

Think that tutorial was updated to remove sendfile: “I used to advise installing sendfile, but it doesnâ??t helpâ??Apache serves the static content, so the 20%-or-so boost on static files is never seenâ??and it can even cause some pretty severe stability issues. So. No sendfile, and if youâ??ve got it installed, uninstall it, pronto. (This comes straight from Zed, who would know such things.)” ---

something unusual in mongrel.log? does it work when you go to your mongrels directly ([http://localhost:8001](http://localhost:8001))? are the files null-sized? what content-length does mongrel return to your browser? 2006/8/10, David S.

Therefore I didn’t realise Sendfile was even there and causing a problem, just a heads up to anyone else hitting a similar problem with HTTP 206 returned for static content. ---

More information might be helpful here… Did the applications work correctly behind Apache when running in webrick or lighttpd? Are you mapping the front-end Apache server to back-end Mongrel apps using a path based scheme ([www.mydomain.com/myapp](http://www.mydomain.com/myapp)) or are you using vhosts ( [myapp.mydomain.com/](http://myapp.mydomain.com/) ) ? ---

Turn on mod\_rewrite logging and make sure that it’s working the way you expect. Most likely some rewrite rule is messing things up or that you’re not actually serving it with apache but instead with mongrel (through apache). – Zed A.
