Subject: [mod-security-users] ModSecurity-NGINX experimental to beta

Hi,

We have just committed a brand new version of NGINX module that has the basic functions for requests treating (header and body). Thus, we have a new beta version of NGINX module.

But we are in need of beta-testers. If problems are detected, please let us know so that we can provide a more stable module for our community.

Actually we don't have a package of NGINX module, you need get it from source via SVN or http in http://mod-security.svn.sourceforge.net/viewvc/mod-security/m2/trunk/ and compile it.

If necessary, we can provide basic instructions for building and testing.

Thanks for help,

Regards,

Alan
