[2.0.2-java] How to route back to previous URL?

[Alex Hanschke]

What is the most elegant way to route back to the client's previous page?

I'm thinking of an application which has a login form on every page and, at some point the client is required to login.
I then want to make sure the login action routes back to the page the user was on.
Any ideas?

Cheers,
Alex

Just include the original URL in the login call. This is a pretty common solution.

/login?from=http://xxx

Thanks Guillaume - just thought there could be a more sophisticated solution, but it'll do the work!

You can also redirect to the referer URL assuming the browser will send this header,

I had this code for Play 1:

        try{ redirect(request.headers.get("referer").values.get(0)); } catch (Exception e) { redirect("/"); } 


It should be difficult to port this for Play 2

(ok my try catch was a bit wrong because it catch the Redirect exception, just to tell that you need to check if referer is available, but it should be easier with scala, in a functional way)

[I am learning play so I have not tried this.]

I know I should just embrace the web, but I believe that loading up the url with query strings is an ugly failure to separate concerns.  So the way I have handled this in other frameworks is to embed the original target (or referrer, or whatever the semantic destination should be) as a hidden field in the login form.  Then, when the user hits submit, my POST action reads the hidden field and does a redirect...assuming successful validation of course.

HTH,
Carlos

I am not sure if i am right but when we try to access the original url directly , we will be taken to the login page and the login page inturn has a reference to the original url (i happened to see in my web application). In that case all you have to do is add the window href location to the form submit action.
