Hello all,

I have a legacy web app that I’m replacing in rails. This app is  
public, so  
I need to over-ride the exising login.jsp that has other external links  
and  
probably many bookmark entries in customer browsers.

So, what I’d like to do is replace the login.jsp with a login.jsp that  
just  
has a redirect to my rails login url… is this possible? Also, one of  
the  
external links passes some params to the jsp as well… can the redirect  
also  
forward those parameters to my rails login url ?

Thanks for your advice!

You could add a AddHandler in your .htaccess file that tells apache to  
render files with a .jsp extension in PHP. That way you could use PHP to  
gather the parameters and do the redirect:

Addhandler php-script .php .jsp

Try something like this in your Rails .htaccess file as the first  
rewrite rule (untested):

RewriteRule ^login.jsp(.\*)$ /your\_login\_controller/your\_login\_action/$1

HI Brad,  
Since I have no PHP knowledge, could you provide an example ?

Thanks.

I used a route to solve this :

map.connect ‘UserLogin.jsp’, :controller=\>“user”,  
:action=\>“remote\_login”

My intent with this change is simply ot send the request into the rails  
app  
and perform processing there (this is a login page from a legacy j2ee  
app).  
So, this route sends the request into my controller just the way I want  
it.

Thanks for your advice Brad!
