Hello folks, I'm using squid 3.1.11-1 on Ubuntu Server 11. I am using "/usr/lib/squid3/squid_kerb_auth" to auth against a Windows 2008 directory. I am unable to upload attachments to emails when using the *new* Yahoo! Mail interface. The old interface seems to work fine. I've seen this problem reported around the internet. These older posts reveals some insight: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-NTML-and-auth-problems-with-POST-td2255704.html http://www.squid-cache.org/mail-archive/squid-users/200506/0158.html I made a "POST_whitelist.txt" for .yahoo.com and uploads work fine. But this is an ugly workaround. More recently, someone also experiencing this issue filed a Firefox bug. But I'm quite sure it's not a Firefox issue: https://bugzilla.mozilla.org/show_bug.cgi?id=679519 Any better fix for this out there? Thanks, Hank
