Re: [squid-users] looking for testers: google maps/earth/youtubecaching

Ok ! Problem went away...
If you are interested, i have one problem here, sometimes squid cached the
video and served it from cache.
But in some cases like this. I watch the video but squid doesn�t have luck
with save it on hard disk.
I tried to watch the video again but it didn�t served it from cache.
Could you please check if i�m wrong ?
Below are my store.log and access.log

Thanks in Advance,

Gleidson Antonio Henriques
