Then I used squidclient, to view the full HTML transactions in progress. # To see what squid was giving out: squidclient http://www.nbs.yu/...... -- gave out the empty page from my cache so purging the locally cached data i tried again squidclient -m PURGE http://www.nbs.yu/...... squidclient http://www.nbs.yu/...... -- and got a proper page from Apache. # To see what the site was giving squidclient -h www.nbs.yu -p 80 http://www.nbs.yu/...... When it worked first time (saying Apache page) I tried it again to be sure and saw the empty page (saying OpenCms page). Repeating another 4 times always brought up the empty page from OpenCms. The output of squidclient is: Request headers clients sends to server/squid <empty line> Reponse headers from the server/squid to client <empty line> page data (if any) Amos
