Hi there!

The question is absolutely legitimate and educating.

Basically the issue is how to programmatically determine the port of your applicaiton after your have registred it, so you could assemble the URL pointing to your specific page. There are two ways of doing that.
One, for .NET applications only, is to use Cassini API implemented in the CassiniConfiguration.dll that can be found in the Cassini application folder. The method is Metabase.FindApplication(Guid appID). It returns ApplicationEntry structure that has Port field in it.

Second way, suitable for any programming language, is to call Cassini configuration web service at http://localhost:7756/CassiniConfigurationService.asmx. It has GetApplicationUrl(Guid appID) and GetApplicationPort(Guid appID) methods, which return the complete application URL, and application port number respectively, for a given application ID.

Best regards,

Could you please fill the ... for me ? How can I set the Guid to my apps Guid ?

Dim mb As CassiniConfiguration.Metabase
Dim ae As CassiniConfiguration.ApplicationEntry
Dim guid As Guid

ae = mb.FindApplication(...)

Questions :
The Guid I have in my application details remain the same once I deploy my installer on another machine ?
Do I have to register my application by actually hardcoding it in my program or does the installer take care of that ?
