I get a 400 bad request - invalid Url when the length of the request exceeds 320+ characters

Question

Not sure what could be the reason. Added the following in Web.config also. maxUrlLength=\"1024\" maxQueryStringLength=\"1024\" requestPathInvalidCharacters=\"\" maxRequestLength

Answer 1

Just documenting my experience:

My issue was the one pointed by @Mark at the question comments:

"by default the maximum url segment length is 260"

He suggested to increase this limit in the registry, but I didn't want this kind of trouble. The suggestion by @Vignesh T worked better:

"Replaced the url segment into a querystring parameter and it worked fine"

In summary, instead of doing:

I just did:

http://path.to.website/?key=very-long-string-goes-here
