xmlhttprequest headers and data

[salimkamboh]

Hi all
I have a little issue. How does the ajax makes request? Does it send headers and data same time or first sends headers and then data/parameters?
If it sends both separately , does it mean that if we don't close connection, we may send parameters again with headers already sent?

Thanx

they both go in one bundle.
