Xpages/Dojo login questions

In the articleAdvanced XPages : A Nicer Domino Login Part 3

in Dec’s Dom Blog, there are a couple of comments on which I am very interested, but no real solution is posted there. As I’m a noob in Xpages and Dojo I’d like som explanation and examples:

* The script library "login" searches for a "GIF" to test for login ( if(String(data).substring(0,3)=="GIF").



While this is OK for Firefox it does NOT work for IE7 (as noted in a comment).



The commenter suggest to look for a "LOGIN" text in a small text file, so I created a LOGIN.txt file with just the word LOGIN in it and now I test for



if(String(data).substring(0,5)=="LOGIN")



=>> it works in IE BUT does NOT work in FIREFOX !!!



Any suggestion how to make it work for BOTH??



* In another comment they say:



"I used your solution even when anynymous is no access. (by redirecting the domcfg login form to an xpage with the popup login). Works like a charm."



Any idea HOW to code for an AUTOMATIC show of the POP-UP Dojo window?!?!?



Moreover it seems to me that you CANNOT tell in domcfg to go DIRECTLY to an XPAGE: I had to redirect to a normal FORM than in turns redirects to the Xpage (on the onLoad event).



Is thi the only way to do it? or is ther a simpler way?
