404 no resource found error due to path variable having a '/' char in its value.

[Saurabh_apg]

I have an proxy flow having condition as <Condition>(proxy.pathsuffix MatchesPath "/eligibleProduct/{folderId}/{contractId}") and (request.verb = "GET"). However user is having the value of contract id like  contractId=XYZ/B due to which request is failing in apigee with 404 no resource found error. How to fix this issue and how can we extract the contract id value including '/' in a new variable.
