No.

This would require inspection of the TCP data secion, and infact an
understanding of HTTP. LVS only has access to TCP headers.

Is there an open source load balancing option that does support cookie based
persistent sessions?

Thanks,
Eric

Hi,

Assuming you are clustering an HTTP service in the 'common' fashion...

LVS --> realservers (+ web server + cgi + cookies) --> backend database

...then do you _really_ need persistence based on individual cookies?

Because your cgi / asp / php / jsp etc... that reads and writes your
cookies will be the same across all the real servers (because you are load
balancing the application / web pages etc...) thus the cookie will provide
the state information (to / from the database) that you need.

If this isn't the case for your web application, could you describe your
situation further?
