Creating an HTML response for URLS with no extensions

[Scott Taylor]

I've just started playing around with Sling, and I would like to try to 
move one of my web applications over to Sling. The application is just a 
set of HTML pages, but it uses URLs without extensions. So instead of 
urls like http://www.mydomain.com/mynode.html I would like to use 
http://www.mydomain.com/mynode/ to return an HTML page. I tried creating 
a GET.esp script, and while that caused an html page to be return when 
no extension was present, it also affected the other extensions as well 
(eg. .json). Basically I would like Sling to treat urls without 
extensions as having an .html extension (but without using a redirect). 
Is that possible? I believe I saw some discussion about this in the 
email archives, but I'm not sure what the outcome was.

Any help greatly appreciated,
