REM "Script to create login/logout link";

MyDB :=@ReplaceSubstring(@Subset(@DbName;-1);"";"/");

@SetTargetFrame("_top");

"[<a href=""+@If(@Name([CN];@UserName) = "Anonymous";

"/"+MyDB+"?OpenDatabase&Login" target=_top>Login</a>]";

"/"+MyDB+"?Logout&Redirectto="+MyDB+"" target=_top>Logout</a>]")

But there are cases where a login link would be useful - where USERS have to authenticate for personalised pages or interactive elements. Like Notes.net really.

I'm not sure I will bother though. I will just put "(Requires Login)" or something on the end of the title attribute of <a> elements that link to bits that require authentication, such as something?OpenForm, or whatever. Then anonymous has reader access and default applies to anyone logged in, and can have author access for interactive areas such as comments or discussion forums. Now that can't be proper English. What's the plural of forum? Can't be Fora, surely? Sounds like Flora and Fauna. Sorry, off-topic there.

Anyway, anyone who clicks one of my "(Requires Login)" links and fails to authenticate will be told by the $$ReturnAuthorizationFailure or $$ReturnAuthenticationFailure form how to "get" a login. Then I will get more subscribers hopefully. My reason for requiring authentication for interactive areas is that I want to run polls/votes/etc that won't show anyone results so far until after they have voted, and won't let them vote twice (unless they are bloody-minded enough to create dual logins in which case they need to get out more).

I don't know if it's possible to create a Login link without using JavaScript. On a document, you can get an equivalent URL to the current URL up to the end of the DocumentUniqueId and maybe add ?Open&Login by using the following formula: "http://" + Server_Name + "/" + @ReplaceSubString( @Subset( @DbName; -1 ); "\\"; "/" ) + "/" + "ViewNameOrNumberZero" + "/" + @Text(@DocumentUniqueId) + "?Open&Login"

I think. On design elements such as views or pages it would be as simple as doing the following: "http://" + Server_Name + "/" + @ReplaceSubString( @Subset( @DbName; -1 ); "\\"; "/" ) + "ViewOrPageName" + "?Open&Login"

I can't be the only person interested in accessibility for non-scriptable browsers. Can I?

Trouble is, even if you login at the .nsf level of the url, IE often 'loses' your credentials.

The only sure way around this I've found is to set a cookie when you login, and then each page checks for the presence of the cookie and appends '&login' to every link it produces in order to force IE to re-send the credentials.

Very messy !

Anyone else had these problems ?

Personally if a lot of different users are going to be using the system, then I'm all for having an actual login link. If it's just for me to use then I don't bother.

I get the += (assignment with operation), and the ? : (conditional operator). Use them all the time. I also use the search method on strings, but only to match regular expressions where it returns "the position of the start of the first substring of string that matches regexp or -1 if no match was found" -- to quote my O'Reilly JS book.

So, would you mind "reading" it to me?

Db := @ReplaceSubstring(@Text(@Subset(@DbName;-1));"\\";"/");

@URLOpen(Db+"?Logout&redirectTo=/"+Db)

javascript:location.href = location.href.substring(0,location.href.indexOf(".nsf")+4) + "/?logout";

Two great tips in as many days... one would think that you're trying to pull ahead of the pack!

...or at least keep your mind off of the recent unpleasentness. ;-)

Thanks again!
