URLRewrite IIS 7 - regex

Question

I am trying to perform a simple URLRewriting. if you visit azamsharp.com it will take to some folder browsing structure it should go to http://www.azamsharp.com/AzamSharpWebApps/Default.aspx.
I don't want to see the AzamSharpWebApps in the URL: Here is the URL Rewrite I am using:
<system.webServer>
<rewrite>
<rules>
<rule name="Virtual Director" enabled="true" stopProcessing="false">
<match url=".*" />
<conditions>
<add input="{MyDomains:{HTTP_HOST}}" pattern="(.+)" />
</conditions>
<action type="Rewrite" url="{C:1}{REQUEST_URI}" />
</rule>
</rules>
<rewriteMaps>
<rewriteMap name="MyDomains">
<add key="azamsharp.com" value="/AzamSharpWebApps/default.aspx" />
<add key="www.azamsharp.com" value="/AzamSharpWebApps/default.aspx" />
</rewriteMap>
</rewriteMaps>
</rewrite>
</system.webServer>

I don't know how IIS UrlRewrite works, but at a general regex level you want to replace ^(?!/AzamSharpWebApps).+ with /AzamSharpWebApps/$0
The ^ is start of string, and the (?!..) is a negative lookahead, saying "make sure the following text is not "/AzamSharpWebApps", and then the .+ matches any character until the end of the string.
In the replace side, the $0 indicates the entire captured text - so basically the regex is saying "if it doesn't already start with "/AzamSharpWebApps", prefix it with that.
(You'll need to experiment with whether you need a / before the $0 or not.)
Anyhow, looks like IIS uses {C:0} instead of $0, just to be different, so I guess it will look something like this inside the rule:
<match url="^(?!/AzamSharpWebApps).+" />
<action type="Rewrite" url="/AzamSharpWebApps{C:0}" />
But possibly it needs more than just that.
