Plz check again the owner/group of the /Cache dirs.
This post describes the exact same problem you face, and it's just a matter of chown the cache dir.

Every thing was done as per your suggestions but still it is not working. Same commands were applied but in vain.

Even created a file swap.state in /Cache1/squid and /Cache2/squid but still not working.

I'm asking you once again: Are you sure it's not a SELinux problem?

Dear what do you mean by SELinux problem. I am using red hat linux enterprise AS 4. I don't know much about SELINUX. So if there be a problem please let me know about it and its solution.


Thank you very much for your active support.

You should read this if you don't know what SELinux is.
Runnig you'll find out the SELinux status.

I am really thankful. You are great. My problem has been solved. You were absolutely right. The problem was SElinux. I found a website and I applied setenforce 0 command and it worked.

Later on I appended selinux=0 to grub.conf and now it is working perfectly.

Glad to see it worked. We would avoid all of this if you had checked about SELinux from the beginning.
Anyway I don't think it's a good idea to disable it completely. You can read the documentation to see how you can add rules to it to do what you want.

Regards

I would read the documentation in detail. If you know about inserting rules without disabling Selinux please let me know about it.

I had no idea of SElinux and i am working on it for the first time.Your help is really appreciated.

I'm sorry but I cannot help you on this, because I have never used a distro that is SELinux enabled.
Better read the documentation

Regards

OK No Problem

Thanks, You have already helped alot.
