I would like to pass to my webservice a datetime parameter using Fiddler. If I simply specify the date https://localhost:44385/api/test/created_start_date/2013-03-21 it works as expected, however when i add the time https://localhost:44385/api/notes/created_start_date/2013-03-21T00:00:00 it crashes with the message A potentially dangerous Request.Path value was detected from the client (:). Is there any workaround to this? I am using ASP.NET Web Api (target framework 4.5.2). Thank you!

That's a well-known issue. Basically a range of special characters including the colon (:) will cause this condition. Is it possible to send the date time as  URL parameter instead of being part of the route?, a workaround might be send ticks instead https://msdn.microsoft.com/en-us/library/system.datetime.ticks(v=vs.110).aspx

To be clear, the server has an ASP.NET feature enabled that rejects colons and other "special" characters; this has nothing to do with Fiddler itself. If you replace the : with %3a, is there a change?
