Error in HTTP connection

Dear experts,

I am configuring cts+ for our EP system.

But when i am creating http connection for ctsdeploy i am getting error " query string not allowed"

data supplied by me is hostname : < targethost>

Path prefix : /DeployProxy/default?style=document

Also i am not able to test connetion when supplying hostname but if i am giving ip of host connection is successfull.

and for both scenario if i supply path prefix getting same error " query string not allowed"

Please help

thanks in advance
