Application URL from within an included module

Application URL from within an included module

  
I would like to have my custom theme contain the header block. In the header block, there is a link to the "home page"...But, GetOwnerURLPath returns the url to the Theme module, not the application...

Is there a way to get the URL of the entry point of the application easily?

Thanks,
Robert
Nevermind...this did the trick
"/" + GetEntryEspaceName()
