Proto Balance SSL negotiates an SSL connection and forwards the plain HTTP connection to your Web server. Certificate management like request generation, vendor certificate installation, and key generation are all done from an easy-to-use Web interface. It load balances connections over multiple Web servers. It performs 1000 SSL transaction per second. Traffic management and on-the-fly redirection of traffic. On-the-fly adding and removal of servers. Traffic accounting and client-connection-rate limits. Denial of server protection. Layer 7 inspection and X-Forwarded-For support.
For high traffic Web sites, Proto Balance Advanced provides connection rate limiting per second and limits the total number of connections. Both are done on a per-client basis. It has a complete Web configuration interface. The IP address of each connecting Web browser is recorded along with its connection stats. It is scalable to millions of clients and handles 10,000 concurrent connections. It performs server backend load balancing with an on-the-fly capability to add and remove servers. Daily and weekly traffic graphs are shown.
txOpenID is an implementation of the OpenID Identity Provider specification, written using Twisted Web and Divmod's Nevow. It reads authentication data and user Web sessions out of a MySQL database using MySQLdb and Twisted Enterprise's adbapi layer. txOpenID currently supports version 1.1 of the OpenID specification.
libapache2-mod-scramble-ip is an Apache 2 module that works like mod_removeip, but instead of just overwriting the IP address with 127.0.0.1, it encrypts the IP address. This way you always get an IP address to work with (in scripts, etc.) and have the ability to use tools like awstats to analyze your logs. It's in alpha status, but working on some Apache 2 servers, and the 'cost' (load) should be small and reasonable.
