I receive a not able to access http error and denied any request from http.

The work around for this is to clean out the cache peridically.

Here are steps to clean out the http cache:

- Webadmin into the box and disable HTTP proxy
- SSH into the box
- goto directory "cd /var/chroot-squid/usr/local/squid/cache"
- remove all the files "rm -rf *"
- Webadmin into the box and enable HTTP proxy
- create the cache directory "/etc/init.d/squid createcache"
