Re: [squid-users] Caching Expired Objects - One Small Step Forward

Hi All,
a small success:
I have set a an apache2.2 server as a proxy without
caching as a parent proxy to my squid. I pass my
youtube video clips through this parent. The apache is
on the same machine as the squid. Using the mod_header
module in apache, I cleaned out all the worrisome
headers in the the youtube clips and now squid caches
them and produces hits.

The only outstanding issue is youtube serves videos
from random servers. I will therefore have to
implement a redirection script so that if a video clip
has already been cached, I will pick that one. I hope
to work on that over the weekend.

I sometimes get about 10% traffic to youtube so if I
can get a descent HIT rate it will be significant to
the overall performance of my squid. Thanks for the
hand-holding, Henrik.

Regards,
solomon.
