问题
In a Grails project I'm trying to map a Url based on whether or not a Fragment Identifier is present in the Url. The Fragment Identifiers are important because a Flash library SWFAddress uses them to communicate to a Flash application present in the web page.
I simply need to determine whether a fragment is present or not in the Request url.
Should I look into HttpServletRequest to do this?
What's the best way in Grails to route a url based on whether a Fragment Identifier is present in a Url?
[I asked this same question at the Grails forum.]
回答1:
A fragment identifier is not part of a URL, it is merely used in conjunction with a URL. It is of value only to the client.
A compliant server will ignore any fragment identifier sent by a client.
You can't design your url mappings based on fragment identifiers, the URL will not contain a fragment identifier by the time it reaches your app.
