Match protocol http - problems in regex

Hello

I have troubles in this:

router(config-cmap)#match protocol http url

*(torrent|thepiratebay|isohunt|entertane|demonoid|btjunkie|mininova|flixflux)* Assertion(text[n+1] == ')') failed at line 606 func parse_atom() file ../inspect/re_regexp.c Assertion(text[n+1] == ')') failed at line 606 func parse_atom() file ../inspect/re_regexp.c Assertion(text[n+1] == ')') failed at line 606 func parse_atom() file ../inspect/re_regexp.c Assertion(text[n+1] == ')') failed at line 606 func parse_atom() file ../inspect/re_regexp.c

and it doesnt work.

I would like to create a class map that drops all http:// *word* (where word is one of this word list). Since I tried to put them one by one but it tells me that the max limit is

24 entries.. I would like to put them in a few of large lines.

(torrentorrent|thepiratebay|isohunt|entertane|demonoid|btjunkie|mininova|flixflu\x) (vertor|h33t|zoozle|bitnova|bitsoup|meganova|fulldls|btbot|fenopy|gpirate) (sumotorrent|bitmonster|azureus|utorrent|vuze|torrentreactor|commonbits) (torrentz|bitlord|warez|bit-torrent)

I am not able to insert them in the match protocol http url I can put them one by one but after the first 24 it stops accepting them. I am working actually (for test) on a C877 48F/256D with 15.0(1)M2 advipservices k9 ios. can you help me ?

I would like to implement them on a C2651xm 48F/256D that will work as single appliance.

thank you
