Normally, if you can send back a tiny response, before you start the processing, then the browser will wait happily for the rest of it to come back...

try putting;

<%
out.flush() ;
%>

before you start the processing...

ITs not browser time out.. its webserver/DNS Server time out

I think somasekhar is suggesting it's squid (a proxy) that's timing out. At the end of the error message is:

A little more information on the squid timeouts:
Request timeout: how long to wait for the start of a response after establishing a connection
http://squid.visolve.com/squid/squid24s1/timeouts.htm#request_timeout

Read timeout: how long to wait for more data, after receiving only first part of a response
http://squid.visolve.com/squid/squid24s1/timeouts.htm#read_timeout

(release notes here: http://mirror.aarnet.edu.au/pub/squid/squid-2/STABLE/squid-2.5.STABLE5-RELEASENOTES.html)
various timeouts adjusted: connect_timeout 1 minute (was 2 minutes which is now forward_timeout), negative_dns_ttl 1 minute (was 5 minutes) and is now also used as minimum positive dns ttl, dns_timeout 2 minutes (was 5 minutes)

If you can't change the configuration of the proxy, you'll have to somehow rewrite your query to execute in stages, outputting some sort of progress message or white-space or something inbetween each stage (followed by out.flush() to keep the connection alive)
