Having recently signed up to Facebook (please don’t hate me) I’ve been trying to add friends, and generally do the rest of the stuff that you do on facebook. Except I ran into a problem with the image verification process.

It always failed after I submitted the verification code, saying I hadn’t entered the correct code. Friends I spoke to didn’t have any problems so it must be me or something to do with my setup here at home.

On a hunch I by-passed Squid and was able to successfully complete an image verification. To test this wasn’t a fluke I reset things back and it failed. I by-passed squid and again it worked.

So if your having problems with facebook and use squid to do your web caching, then be aware of this problem. I’m going to investigate this and try and work out why this is happening as I never have any problems with other sites.
