Hi everyone! I use squid with our ISP services. And now we use storeurl_rewrite_program for rewrite some video cache for our user. But after a few days draggle and google. We found it's so difficult for us to do this. I can't find where is the error of my configuration.And i hope someone can help. This is my core thing about the rewrite program. The squid.conf acl store_rewrite_list referer_regex ^http://static.youku.com/.*$ storeurl_access allow store_rewrite_list storeurl_access deny all storeurl_rewrite_program /var/squid/run/squid/store_url_rewrite.py ------------------------ this is my store_url_rewrite.py ------------------------- #!/usr/bin/env python import re import sys YOUKU=re.compile("http://\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/youku/.*/(.*-.*-.*-.*-.*)\?.*") def modify_url(line): list = line.split(' ') old_url = list[0] new_url = '\n' is_match = YOUKU.search(old_url) if is_match: new_url='http://www.youku.com/'+is_match.group(1)+new_url return new_url while True: line = sys.stdin.readline().strip() new_url = modify_url(line) if new_url: sys.stdout.write(new_url) sys.stderr.write("\n\nREWRITE:"+new_url+'\nORI:'+line) else: sys.stdout.write(line+'\n') sys.stderr.write("NOREWRITE:"+line+'\n') sys.stdout.flush() ------------------------------------ throught the stderr , I can find the new_url already write to the log file.But I can't found the it in the store.log The cache.log REWRITE:http://www.youku.com/030002050050BCAFBB490B03BAF2B1A20A79FD-0282-DEA6-350C-E810E14BAA19.flv ORI:http://118.180.3.36/youku/6971A9C8A1E348250177A4314B/030002050050BCAFBB490B03BAF2B1A20A79FD-0282-DEA6-350C-E810E14BAA19.flv?start=17 192.168.108.14/- - GET - myip=192.168.137.20 myport=3128 But there is no object http://www.youku.com/030002050050BCAFBB490B03BAF2B1A20A79FD-0282-DEA6-350C-E810E14BAA19.flv in store.log Thanks for your help!
