Help!! RedirectFromLoginPage and GetRedirectUrl

[Guest]

Any help anyone can give me will be appreciated!!!! This is driving me
c-r-a-z-y!

All I can get from both of the above redirections is a redirect to a page
named default.aspx. How do I make either of these work? I have an app that
has two pages that need a login. I need to be able to have it automatically
return to whichever page the user came from.

I've tried both of the following (not together, of course):
[Button Submit has code to check database]
FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, False)

[Button Submit has code to check database]
Response.Redirect(FormsAuthentication.GetRedirectUrl(txtUserName.Text, False))

My Web Config has this in it:

<authentication mode="Forms" >
<forms name=".LoginCookie" loginUrl="Login.aspx"
protection="All" timeout="40" path="/" />
</authentication>
(Although I would rather not rely on cookies since people can turn them off,
but I got this from an example in a book and couldn't find an example of how
to do it without cookies.)

I made sure in IIS the app was an app.

I originally had one of the pages in a separate folder. I thought maybe
that had something to do with it, so I cut and pasted it to the first level.
That did nothing.

Again, any suggestions will be greatly appreciated!

Thanks so much for your response.

The problem is not getting to the login page. It is the redirecting back to
the original page they came from.

The RedirectFromLoginPage and GetRedirectUrl are supposed to, as a fellow
programmer put it, "automagically" redirect back to the page that took them
to the login page. As I understand it, from all the reading I've done, both
in books and on the Internet, he is entirely correct . . . however, for some
reason my machine seems to have a mind of its own and is not responding
correctly. (Of course, I blame it on my box, but we both know who's the
smarter of the two . . .guess I'm doing something dumb - I haven't found an
instance where anyone has had a problem with this.)

Can you give me another clue?

Again, thanks so much for your response! This is sooooo frustrating!

For what it'e worth, the redirect back to the selected page before login,
doesn't work for me either.

TJS -

Thanks again for your response! At least I know I'm not the only one . . .
Now, how do we go about getting a double-help out there on this one?????

Sandy,

If everything else fails, you can append the current page's encoded URL to
your login page's URL(i.e.: Response.Redirect("login.aspx?currpage=" +
HttpUtility.UrlEncode(Request.RawUrl))).

When authenication success, redirect the user using
Response.Redirect(HttpUtility.UrlDecode(Request.QueryString["currpage"]));

When ASP.Net redirects you to the login page, it should append something
to the request URL so that the full url looks something like:
http://www.domain.com/login.aspx?ReturnUrl=/PreviousPage.aspx%
3f__redir%3d1&__redir=1

the appended query variables :

ReturnUrl=%2fPreviousPage.aspx%3f__redir%3d1

are an url-encoded form of :

ReturnURL=/PreviousPage.aspx?__redir=1

which is what the RedirectFromLoginPage and GetRedirectUrl methods will
use to decide where to redirect to.

Maybe these aren't present on the redirect-to-login-page URL? this would
explain why you're unable to return to the original page.

Lee -

Thank you for your response. Would you happen to have an example of what I
would put in my Login.aspx page code and what I would put in my
AddNewListing.aspx code?

 

[Guest]

Lau -

Thanks for the suggestions! I did try the
Response.Redirect("login.aspx?currpage=" +
HttpUtility.UrlEncode(Request.RawUrl))) with success. My redirect included
the correct info in the browser url address.

When I tried to use the other one, in my Login page to redirect back to the
AddNewListing page, I got the blue squiggly line under it. What dumb thing
am I neglecting to do?
