Question

My ‘LocalClient’ app is in a corporate LAN behind an HTTP proxy server (ISA). The first Azure API call i make – CloudQueue.CreateIfNotExist() – causes an exception: (407) Proxy Authentication Required. I tried following things:

• Added the <System.Net> defaultProxy element to app.config, but it doesn’t seem to be working (Reference: http://geekswithblogs.net/mnf/archive/2006/03/08/71663.aspx).
• I configured ‘Microsoft Firewall Client for ISA Server’, but that did not help either.
• Used a custom proxy handler as suggested here: http://dunnry.com/blog/2010/01/25/SupportingBasicAuthProxies.aspx. I am not able to get this working – getting a Configuration initialization exception.

As per MSDN, an HTTP proxy server can be specified in the connection string only in case of Development Storage (see http://msdn.microsoft.com/en-us/library/ee758697.aspx):
UseDevelopmentStorage=true;DevelopmentStorageProxyUri=http://myProxyUri

Is there any way to connect to the Azure Storage thru a proxy server?

Answer 1

The custom proxy solution (the third thing i tried as mentioned in my original question) worked perfectly. The mistake i was doing earlier was not putting the <configSections> element at the beginning of <configuration> in app.config as required. On doing that, the custom proxy solution given here solved my problem.
