How to increase the size of HTTP Post Request in Websphere

The HTTP specification doesn't impose a specific size limit for posts. They will usually be limited by either the web server or the programming technology used to process the form submission.

DNS is the time it takes for gethostbyname() to answer. It is the time that it takes for the hostname to get resolved. It depends on DNS server, network latency and DNS caches.

Connect is the time it takes to make the TCP connection. It depends on the network (end-to-end latency). For SSL add also the time it takes to establish the encrypted tunnel.

Send is the time it takes to send the HTTP request and can the client can see if the data was send because it is receiving ACKs from the remote server.

Wait is the time that it takes for the remote server to process the request. No network is involved.

Receive is the time it takes to receive the HTTP response (the header and the data).

You will have some important events when the header was received, when the server has flushed the partial output and when the entire content was received - some of them triggers JavaScript events.
