Sticky connections do not work

[eug_k]

Hi guys!

I am trying to configure dispatcher module to use stiky connection for two pages:

/content/mysite/en/event/main.html
/content/mysite/en/event/login.html

So I added to dispatcher.any this code:

/stickyConnectionsFor "/content/mysite/en/event"
After it I restarted apache, opened a page /content/mysite/en/event/main.html in browser and saw that renderId cookie was set. Also in dispatcher.log there was this message:

Setting sticky connection to publisher_pub1
response.headers[Set-Cookie] = "renderid=publisher_pub1; path=/content/mysite/en/event;"
But when I reloaded the page and dispatcher sent my request to another publisher. New renderId cookie was set, in dispatcher log there was:

Setting sticky connection to publisher_pub1
response.headers[Set-Cookie] = "renderid=publisher_pub2; path=/content/mysite/en/event;"
Seems like dispatcher just does not read the renderId cookie and serves requests irrespective of it.

I use Apache web server version 2.2 and dispatcher module version 4.1.4. I used dispatcher 4.1.1, update it, but it did not help. Also I tried to switch off apache mod_security, it did not help too.

Could you help me, please.

Have you by any chance configured failover in dispatcher.any ?

seem like no, here is my dispatcher.any file

Your cookie & config looks right to me. Please try [1] & also file daycare ticket.

[1]  

*   At start of dispatcher did you see message "Sticky Connections enabled"

*   Just as a trial can you rename the renderid with underscore & see if it works. Just suspecting is the parser considering underscore to be a separator.

*     One more trial try with

 /stickyConnections {
  /paths {
    "/content/mysite/en/event"
  }
}

Thanks you for reply!

1) Yes, I see

Sticky Connections enabled below /content/mysite/en/event for farm: mysite

2) I deleted underscore, did not help

3) seems like it is not valid config, because I did not see cookie renderid after I set this like you suggest

OK, I will contact with support.

I found it is works when I set sticky connections for the root of my site:

/stickyConnectionsFor "/"

But I need it for particular pages only.

Also we set url mapping for resource resolver

/content/mysite/en/</

And I request pages under /content/mysite/en/event like

http://www.example.com/event/login.html

Could it be the reason of the issue?

How I need to configure sticky connections in this case?

/stickyConnectionsFor "/event" /stickyConnectionsFor "*/event"

Both variants above do not work.
