Hi there!
Default document is not the same thing as a "start page". Default document is a document in the folder that will be served if URL points to the folder, omitting the document. Therefore, default document cannot be in another folder. Ability to specify default document in another folder was a
bug fixed in build 7.
To accomplish what we think you wanted to do, you will need to create a redirect page that will take users to src/Default.aspx, place that redirect page under your application root and make it the default document.
