Re: A patch for haproxy 1.3.15.7 (HTTP-ECV)

Yes Willy, I missed the ACL framework. If we re-use ACLs, we can directly reuse all the available keywords, and have less work to do.I don't know how many people doing the development now, and is there someone writing code for this feature.

Additionally, I want to setup a Chinese site(www.haproxy.org), can you add a link to your website.how can I mirror your site and get updated timely.It will be my greatest honor to get supports from you.

i'm sorry, maybe this domain name should be used by your offcial site. :-)
