${flowExecutionUrl} generating invalid URL

All,
Using SWF 2.3.0.RELEASE. When I go to my flow url to start the webflow (e.g. http://example.com/appname/flowname), it does the redirect thing but then goes to http://example.com//appname/flowname?execution=e1s1 (notice the double '//'), and then I get the "too many redirects" error in my browser. If I then remove one of the slashes, the page renders, but inside the jsp, where I have ${flowExecutionUrl} it gets evaluated to //appname/flowname?execution=e1s1 again.

How/where does the flowExecutionUrl get created, and how/why is it adding a double slash?

Hello

Could you post your SWF settings configuration?
