[squid-users] Problems with downloads

Hi everyone,

I have Squid3.0STABLE9 installed on a CentOS5.2_x86_64 system. I have
problems with downloads, especially large files. Usually downloads are slow
in my network because of the amount of users I have but I dealt with it
using download accelerators like “FlashGET”. Now the downloads get
interrupted and they never resume and I don’t know why. I can’t seem to find
a pattern as to when or why the downloads get interrupted. I don’t know if I
explained my self well enough. I’m suspecting that there is something wrong
with all the configurations I did to tune de cache effectiveness. This is
the configuration I have. I left out all of my ACLs since I presume they are
not very helpful in this case. I would really appreciate any help I can get.
Thanks.
