regex - Htaccess Not Working - Redirect 301 -

due bad urls, generated links don't work , want redirect them 301 redirect clear webmaster tools issues google.

so, have url this:

http://www.site.com/subdomain/z//-products 

*note subdomain variable, rest of url static.

as side note, url makes no sense, that's why want redirect it. should this:

http://www.site.com/bedroom/z/12345/bedroom-furniture-products 

anyway, had these bad urls being dynamically generated. we've fixed them, google picked them , keeps trying crawl them. want create htaccess rule 301 redirect them , issue should wash out eventually.

here's tried htaccess no avail:

^(.*)/n//-products/?$ $1 [r=301,b] 

i've tried kinds of permutations of , it's not working. suspected entity escaping issue, research led me add [b], didn't seem work either. it's redirect rule working, it's redirecting original page.

what missing here?

i believe anubhava correct, in there inconsistency between sample url describe /subdomain/z//-products , rewriterule attempted apply. not sure if typo or not. may case copy/paste operation added "/n" literally.

anyhoo, let presume want make rule work /subdomain/z//-products:

rewriterule ^/([^/]+)/z//\-products/?$ http://www.site.com/$1 [r=301] 

see the example 1 slides of pdf quick first portion. faster using (.*).

we literally match z character , surrounding slashes. escape - character, rest of url , optionally match trailing slash. use, if memory serves correctly, "external" style redirect robots re-open separate http connection, appending matched backreference, , hand off status code.

let me know if works.
