[squid-users] How to increase TCP-HIT ratio

Hello

I have two questions.
I discovered cache manager outputs and found that just 5-7% of hits
are served from cache. It is to few. I there any way to increase this
ratio ? My config is bellow.

Second question is about images. Sometimes, images are not loaded.
Mozilla FireFox says timeout, MSIE showx red cross in square. When user
do right click and show picture, image is always loaded. In access log
is not any antry about that image. Just after used show image, than
there is entry about success of download that image.

Any ideas ?

Thanks

Michal
