Hi,
I'm building a tagging system for a site of mine and encountered a problem with a rule for rewriting URLs, using mod_rewrite.
The rule I was using was
but it just didn't work at all ... the
$1 was replaced with nothing "";
So (after hours of searching

) I've changed the rule to
and it works.
The difference between those two is tiny ( from "^tag/..." to "^tag
s/..");
Could someone explain to me why did this happen?
Why using 3-letter-short (or less) words in the pattern screws everything up?
Btw... have a great weekend!
