So came into a problem of url encoding in IIS 7 where it does not like “+”, “/” in the Url. Basically a Url that looks like of like this

I know you may say what is this??? Its actually some kind of encrypted data that is in base64, but since IIS 7 does not like “+” or “/” even if its url encoded.

Here is the code so maybe someday it would help you out also.

And always there should be a test for it.

There are other ways of fixing this and one can read them at
