Symphony.

How to set up Symphony so that the starting page immediately get url parameter so that if index is {$root} site immediately started from {$root}/category

You can add URL Parameters to your home page, but they would need to be accessed as:

/home/:param

Thankfully you can use the Root page params extension to do this :-)

Where can I set it up??? I’ve installed the extension, have chosen the page can’t get what’s next.

Where can I set it up???

From the README:

To set this page, go to the system->preferences page, and select the page from there

I’ve installed the extension, have chosen the page

Where to set the parameters?

May be I’ve put it in a wrong way. Again. I need it so that when a person enters the site url into browser he emmediately gets to the page with the params set up.

Like I enter http://ibcico.com And in browser i get something like http://ibcico.com/about/1/

I see! I didn’t understand that before. In which case you could write an .htaccess rule to send a 301 redirect.
