Change site URL in workflow context

Hi

I have developed a workflow on a sharepoint site. The site is getting accessed with two different url. First url is local url meant for development and second url is the url published for intranet users.

Currently workflow links are pointing to local url even if workflow is run with second url.

first url is http://tgsdnsp707/teams/mysite

second url is http://environment.co.in/teams/mysite

I expect all the url starting with http://tgsdnsp707/ should be altered andhttp://tgsdnsp707/ be replaced withhttp://environment.co.in automatically.

Is there something to do with workflow configuration files? Or this is network setup related issue? Any help appricited.

Thanks
