Thanks that was a mistake indeed. Apart from this I found some thing which I feel is the root cause of the entire problem When my proxy pass entries look as follows ProxyPass /app1 http://192.168.1.3:8080/app1 ProxyPass / http://192.168.1.3 ProxyPassReverse /app1 http://192.168.1.3:8080/app1 ProxyPassReverse / http://192.168.1.3 then some one from internet is able to access the sites.But from within LAN people are unable to access it. How ever if I use ProxyPass /app1 http://site1.myserver.com:8080/app1 ProxyPass / http://site1.myserver.com ProxyPassReverse /app1 http://site1.myserver.com:8080/app1 ProxyPassReverse / http://site1.myserver.com then things work on LAN but from internet it is not accessible and errors are the ones I mentioned while starting the thread. What can be a solution in this case as I do not have a DNS at my disposal I am simply not allowed to have one. Is there any other way because my websites are inside a corporate LAN whose domain name is different from the ones I mentioned above as myserver.com --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
