Re: getting parameters from j_security_check form

Chris, thanks for the quick reply!  As it happens I actually just 
finished method #1 -- in this case I just needed the filter to set a 
session attribute from the extra parameter in the login form, which 
appears to be working.  If it starts to cause problems or get hairy 
later, I'll take a look at FlexibleSecurityRealm too.
