Problems with parameter length in Web Server IIS 7.0 on Windows Server 2008 RRS feed

  • Question

  • Hi,

    We have an IIS 7.0 on Windows Server 2008 which redirects requests to a Web app installed on a Tomcat in the same machine. We have a problem administering the application permissions: when we add an user to severak projects, the request made is like this:

    POST /checking/ajax/admin/permissions/savePermissions.run?user=CENTRAL%5Cfernandasp&rules=p_scripts%3A%2Cp_models%3A%2Cp_projects%3A%2BA%2FHerramienta%20de%20Comprador%0A%2BA%2FHerramienta%20de%20Comprador%2F*%0A%2BA%2FMaestro%20de%20Articulos%0A%2BA%2FMaestro%20de%20Articulos%2F*%0A%2BA%2FSAM%20Aduanas%0A%2BA%2FSAM%20Aduanas%2F* HTTP/1.1

    Parameter "rules" contains the list of all projects, but when this list is too long (longer than 1024 characters), the IIS Server returns a 404 code.

    I have read that 1024 is the default limit for parameter length on POST request, and the way to tune this is by creating the MaxClientRequestBuffer entry in Windows registry.

    I tryed doing that, rebooting the server and the system several times, but it does not work...

    ¿Any ideas?

    Thank you!!

    Based on your description, it appears that the issue is more related to IIS. So I would recommend that you repost your question at IIS forum. Your understanding is highly appreciated.
