hi,  
my url after performing a call to a database looks like this:

[http://localhost:3000/myapp/view?scat=3&mcat=4](http://localhost:3000/myapp/view?scat=3&mcat=4)

is there a way to chop off the “?scat=3&mcat=4” part of the url?

How about

url.sub(/?.\*/, ‘’)

Example:

irb(main):015:0\> url = ‘[http://localhost:3000/myapp/view?scat=3&mcat=4](http://localhost:3000/myapp/view?scat=3&mcat=4)’  
=\> “[http://localhost:3000/myapp/view?scat=3&mcat=4](http://localhost:3000/myapp/view?scat=3&mcat=4)”  
irb(main):016:0\> url.sub(/?.\*/, ‘’)  
=\> “[http://localhost:3000/myapp/view](http://localhost:3000/myapp/view)”

Proper ? should normally arrive escaped in the URL.

Can you fetch that page via POST instead of GET? The latter sends the  
display data as a batch of variables inside the POSTing message, not as  
part  
of the URL.

Your calling function might have a :method option to switch to ‘post’.
