Is it possible to specify proxy credentials in your web config

Question

I need to configure a website to access a webservice on another machine  via a proxy   I can configure the website to use a proxy  but I can t find a way of specifying the credentials that the proxy requires  is that possible   Here is my current configuration    lt defaultProxy useDefaultCredentials  false  gt       lt proxy usesystemdefault  true  proxyaddress   lt proxy address gt   bypassonlocal  true    gt   lt  defaultProxy gt    I know you can do this via code  but the software the website is running is a closed-source CMS so I can t do this   Is there any way to do this   MSDN isn t helping me much

You can specify credentials by adding a new Generic Credential of your proxy server in Windows Credentials Manager:

1 In Web.config

<system.net>    
<defaultProxy enabled="true" useDefaultCredentials="true">      
<proxy usesystemdefault="True" />      
</defaultProxy>    
</system.net>

In Credential Manager >> Add a Generic Credential

Internet or network address: your proxy address
User name: your user name
Password: you pass

This configuration worked for me, without change the code.

Yes  it is possible to specify your own credentials without modifying the current code  It requires a small piece of code from your part though   Create an assembly called SomeAssembly dll with this class    namespace SomeNameSpace       public class MyProxy   IWebProxy               public ICredentials Credentials                       get   return new NetworkCredential  user    password                    or get   return new NetworkCredential  user    password   domain                  set                        public Uri GetProxy Uri destination                        return new Uri  http   my proxy 8080                       public bool IsBypassed Uri host                        return false                      Add this to your config file     lt defaultProxy enabled  true  useDefaultCredentials  false  gt     lt module type    SomeNameSpace MyProxy  SomeAssembly    gt   lt  defaultProxy gt    This  injects  a new proxy in the list  and because there are no default credentials  the WebRequest class will call your code first and request your own credentials  You will need to place the assemble SomeAssembly in the bin directory of your CMS application   This is a somehow static code  and to get all strings like the user  password and URL  you might either need to implement your own ConfigurationSection  or add some information in the AppSettings  which is far more easier

While I haven t found a good way to specify proxy network credentials in the web config  you might find that you can still use a non-coding solution  by including this in your web config      lt system net gt       lt defaultProxy useDefaultCredentials  true  gt         lt proxy proxyaddress  proxyAddress  usesystemdefault  True   gt       lt  defaultProxy gt     lt  system net gt    The key ingredient in getting this going  is to change the IIS settings  ensuring the account that runs the process has access to the proxy server  If your process is running under LocalService  or NetworkService  then this probably won t work  Chances are  you ll want a domain account
