I want to put a link on every page that gets you the OPML version of the page. The back-end just looks for a format param whose value is opml. The question is what's the easiest way to specify that.
I could provide the fully qualified URL -- http://threads.scripting.com/41912ByDw/questionAboutUrls
Or I could leave out the host -- /41912ByDw/questionAboutUrls
Or I could leave out the path -- questionAboutUrls
But could I leave out everything?
It seems to work in Firefox.
Is it kosher?
PS: I added the feature. Click the orange XML icon at the bottom of this page you get the OPML.
