Rails - Jul 2005 - Customizing extension of cached pages

Hi all,

I am starting to play with page caching and while it is working, I''m  
curious if there is an easier way.

I have a Util controller that generates a single JS file from many  
smaller ones s.t. the page only requires one request to the server to  
get all the JS code.  I thought this was an excellent candidate for  
page caching and added the following to my controller:

     caches_page :store_js

Now, it cached the file under public/util as expected, but it was  
given an html extension.  This causes a problem because if I request  
simply /util/store_js, the Rails code runs and re-generates the  
file.  If I request /util/store_js.html, it works __if it was already  
cached__.  If the page was not already cached, I get a "no action  
responded to this request".

To ensure the controller would be called during a cache-miss, I  
fiddled with the routes.rb to map the ".html" request to the real  
controller:

     map.connect ''/util/store_js.html'', :controller =>  
''util'', :action => ''store_js''

And in the HTML I have the following funny-looking JS include statement:

     <script src="/util/store_js.html"
type="text/javascript"></script>


I would like to get rid of the entry in routes.rb, but most  
importantly I would like to have the page cached with a "js"  
extension.  Is this possible?

Thanks in advance,
--Dave.

I found this when Googling a few days ago:

I guess Scott is on the mailing list, if so, thanks Scott! :-)
