Configuration problem ...

Hi !

I configured a squid 2.6 in a debian box (1Gb ram and 120Gb of disk)

When I send a http request to a file bigger than 200kb (my
maximum_object_size is 4194304 bytes and my
maximum_object_size_in_memory 204800 bytes), the squid answers with a
TCP_MISS and It doesn't save the file into the cache.
The size of the file is 210133 bytes.

In addition to this, when I send a http request from the same file,
with different extensions (one with .jpg and other with .gif) the
squid responds in diferent ways. When I sent the .jpg file request, I
receive a "X-Cache" and "X-Cache-Lookup" MISS. When I sent the .gif
file request, I receive a "X-Cache" MISS and "X-Cache-Lookup" HIT.

The follow example shows this issue:

could you check my squid.conf configuration file, in order to detect
some configuration mistakes?

I would thanks your help.

Thanks a lot !!!!
