In my Web Config I have the following User role defined:
      <httpProtocol>
          <customHeaders>
              <add name="RoleOfUser" value="Administrator" />
          </customHeaders> 
      </httpProtocol>

Open in new window


I need to know how to retrieve the value of the User Role of Administrator using the Request.Headers["RoleOfUser"] using C# programming language.

Thanks,

Dan

The purpose of the <customHeader /> section is to have IIS spit out into the server response whichever headers you define. Response headers don't get sent back to the server by the client, so it really doesn't make sense why you would want to use this approach to tagging your user with a role. Aside from that, sometimes custom headers get stripped by middle-tier hardware sitting between your server and the client, so they may not be 100% reliable. Have you considered using cookies instead?

While @kaufmed makes an excellent point in answer to your question


using (ServerManager serverManager = new ServerManager())
      {
         Configuration config = serverManager.GetWebConfiguration("Default Web Site");
         ConfigurationSection httpProtocolSection = config.GetSection("system.webServer/httpProtocol");
         ConfigurationElementCollection customHeadersCollection = httpProtocolSection.GetCollection("customHeaders");
         // Get value from collection here
      }

Michael's code is valid code, but it's not actually reading a value from the request header; rather it's reading the value directly from the config file. If that's what you want, then his code is suited for the task, but if you were expecting to get the value from the request header, which is what I thought your original question was implying, then my previous post applies.

Just reread the question and realised I got side-tracked by the Web.Config section posted and went running off down a tangent. Sorry if I confused the issue but as noted (correctly!) by @kaufmed my code will only read your config file and not the request header.
