[lvs-users] Problems with persistent connections

Hi Folks, firstly sorry for my poor english, rsrsrs. I'm having the following problem: I have six web servers and two machines as balanceadores load (a master and backup). I have some web applications that when are used have the following problem, when users logon they are redirected to the screen logon.
This is because the new requests are redirected to other servers that has no history of the sessions of users, then I added the attribute "persistent = 300" (tested with other major and minor TIMES), solving this problem but creating another:the home page does not load, someone knows how to solve?

PS.: Follows the guidelines from site: http://www.howtoforge.com/high_availability_loadbalanced_apache_cluster

virtual=192.168.6.240:80 real=192.168.6.2:80->192.168.6.7:80 gate fallback=127.0.0.1:80 gate service=http request="index.html" receive="Test Page" scheduler=rr (tested with other algorithms) persistent=600 netmask=255.255.255.255 protocol=tcp checktype=negotiate

persistence creates a lot of problems. Your setup
redirecting connections to the screen logon (which I don't
understand) seems to be part of the problem.

Hey, guys

I have the same problem, that is,

I Followed the guideline:
http://www.howtoforge.com/high_availability_loadbalanced_apache_cluster

1. SITUATION ONE: (I don´t use PERSISTENT = 300 in ldirectord.cf)

and when the users (in yours browsers) access (redirect by load
balance) pages with session controller(user/password), your
requisitions are redirecting to any www servers, always ....

Why? established a connection browser <--> www server, it should not
remain until the closing of the browser?

2. SITUATION TWO: (Now I´m using PERSISTENT = 300 in ldirectord.cf)

Now, SOME users (in browser) receive a blank page,
when they are accessing pages with session controller (user/password).

This is the problem I am having with the ldirector (ultramonkey)!!
