mod_rewrite - Redirection problem: how do I map Ids ?

Hi,
I'm new with mod_rewrite and I'm having a problem.
I need to redirect
mysite/en/guides?country=275
to
mysite/en/guides/Italy

The question is: how could I map 275 to Italy ?

ps: I'm using mod_rewrite.

mod_rewrite is only the first part. You can get the value "Italy" to a script, and the script determines the country number.

Generic solution:

So say guides.foo is the script you have now. It takes the "country" from the URL. Make it also take the country name (however you decide to do that), then use URL rewriting to turn /guides/XYZ into /guides?whatever=XYZ.

Specific solution:

Apache can do that specific URL right out of the box, as long as /guides is an actual file (like guides.php). With

/guides/Italy will automatically go to /guides.php. To get to it you look at the CGI PATH_INFO value, which will have "/Italy". Remove the slash, look up the ID corresponding to the county, and you're done. (Or just use different SQL queries or whatever that look at the county name instead of its ID.)


If you need help with the script, be sure to mention what language its uses: PHP, Python, Perl, etc.

I don't follow you
I'm using rails, but I would like to solve this at server level.
How do I look at CGI PATH_INFO value ?
I think that maybe RewriteMap could be a solution, don't you agree?

RewriteMap could work but is often harder to set up than the simple RewriteRule version.

I'm sure Rails eats this kind of stuff for breakfast. Moving...
