Adobe - metafile download failed

[spies]

Hi All,

I'm using pfsense as a router with squid3 (transparent mode) and antivirus packages installed, everything is fine except the installers from Adobe error out with "metafile download failed".

The antivirus widget isn't showing it having blocked anything and so I'm not sure whether the problem lies with squid or ClamAV.

Could anyone give me a suggestion as what to try first?

Try disabling those services altogether and see if you can download successfully.  If you can, then turn the services on one by one until you find the problem.

It looks like it's HAVP as when I remove never_direct allow all;cache_peer 127.0.0.1 parent 3125 0 name=havp no-query no-digest no-netdb-exchange default; from the integrations box, it then successfully downloads.

I've now added .adobe.com/ to the whitelist and it seems to be working fine.

Any ideas why this is happening in the first place? Detect broken executables is turned off.
