ASP.NET Location Node in web.config

Just a quick one today! This has probably been around for a while now but yesterday I had good cause to use this handy piece of functionality!

The location tag within the web config file of your asp.net 4 website allows you to specify a location tag with a path attribute and set "web.config" style setting for just that single location! This is particularly handy if you need to set request upload limits or request validation settings for a particular page that handles file uploads or downloads.

Here is an example which allows for the upload of very large files and allows a URL Encoded filename (with some very odd characters) to be downloaded


  
  <location path="somefolder/download-resource-page.aspx" allowOverride="false">
    <system.web>
      <httpRuntime requestValidationMode="2.0" executionTimeout="3600" maxRequestLength="1048576" requestPathInvalidCharacters="" />
      <pages validateRequest="false" />
    </system.web>
  </location>



This location section should be placed within the <configuration> tags!
