I am connection to a remote server using Sockets this working fine for WWW IAP
When I try to connect server using MMS IAP it reporting time out error.
After some r&d I found that My MMS iap has proxy,and I have to use proxy filter
I changed my app to RHTTP and I included the proxy filter

CHttpFilterProxyInterface::InstallFilterL (iSession);

Now my app working on mms iap also.
But I want to implement same thing

In sockets. Piz give me some suggestion.
