Hi,
One more thing I forgot to ask.
Right now I am using curl_lib version 7.15.1 and my application don't make
use of curl_multi interface. Is it possible that the curl_easy_perform error
"couldn't connect to host" (on making rapid web requests) will be resolved
with curl_multi interface??
Please give some feedback. Thanks in advance.

Partha.
