Re: [squid-users] Caching file using squid

I managed to save the files from YouTube, it was the refresh_pattern problem,
of course. Removed the acl thingy to save all of minimum_object_size 1M, and
added refresh_pattern:
refresh_pattern . 10080 990% 999999 override-expire override-lastmod ignore-
no-cache ignore-private ignore-reload reload-into-ims

And it does save the files from YouTube:
1234369228.093 SWAPOUT 00 000002DF C9634D246260758A945C786CC86F3965 200
1234368874 1206456375 1234372474 video/x-flv 3825405/3825405 GET
http://v18.cache.googlevideo.com/videoplayback?

expire=1234390473&key=yt1&ipbits=0

But when i try another size with some HTTP-headers that seem problematic it
does not cache:
HTTP/1.1 200 OK
Server: nginx/0.6.31

Connection: keep-alive
Cache-Control: no-cache, must-revalidate, no-store
Accept-Ranges: bytes

1. I thought that the refresh pattern i made covers it all - did i neglect
an option? If not, can it be the fact that i'm running the windows 2.7
version and not the 3.0 (that is only stable for Linux)?

2. Is there a way to debug the squid in order to see why it does not cache -
what prevents it from caching a certain file?

Regards,
Snayit
