Rewriting URL while preserving GET parameters

[kajsng]

Hey. I need help rewriting a url and keeping the GET parameters. I need to rewrite:
/info/info2/anypage.php?something=5 to /info/anypage.php?something=5&id=2

The problem is that "?something=5" is optional. If I do a rewrite that always adds "&id=[the_number]" to the end, if the user leaves out "?something=5" then the request would be invalid ("/info/anypage.php&id=2", should be "/info/anypage.php?id=2").

How can I do that?

See the mod_rewrite documentation [httpd.apache.org], specifically, the [QSA] flag (Query String Append) of RewriteRule.
