response comming slowly from http server via synchronous connection

[preeti.sharma]

My application (in ATL) works for giving suggestions in hindi as user write words.For every character in a word it brings a response (related suggestins of that word) from the server.like suggestions for aap are aap,aapa,aapne aapka ,aapke etc.i have created thread on every char that each time connects to the http server (via sunchronous connection )and brings response.
now i want to find a way to speed up the comming of these suggestions.
shud i us asynchronous connection or is thr any other way.
