Question

I`m using Asp Net Mvc 4 Web Api and I need to make request with querystring length > 2000 symbols

I`ve allready set maxQueryStringLength=”10000″ parameter in web.config.
Everything works well on my developer machine
On IIS it works only if querystring < 2000 symbols,
but if querystring > 2000 symbols I get an error: 404 Not Found

Any considerations?

Answer 1

Have you also set the maxUrl length?

maxUrl Optional uint attribute.

Specifies maximum length of the URL, in bytes.

The default value is 4096.
