Varnish director stickyness expiry/timeout
|
|
Hello,
For a web shop project I am using varnish for loadbalancing (and caching
of course) several web servers.
When it comes to session stickyness I am using the client.ip stickyness
of the backend director.
In vcl_recv:
## Use ClientIP for loadbalancer stickyness (and regard SSL offloading)
if (req.http.X-Forwarded-Proto ~ "https") {
set req.http.X-Client-Identity = req.http.X-Forwarded-For;
if (req.http.X-Client-Identity ~ "\,") {
set req.http.X-Client-Identity =
regsuball(req.http.X-Client-Identity, "\s\,.*$", "");
}
}
else {
set req.http.X-Client-Identity = client.ip;
}
set client.identity = req.http.X-Client-Identity;
It seems that when a customer resturns after approximately 30 minutes
the stickyness is lost and the customer needs to login again.
Is there any timeout / expiry value I can change in order to prolong the
director stickyness?
What I've found is the sess_timeout value which is configured to be 5
seconds as a default value
which doesn't fit our experience but still sounds somehow like the wrong
place.
Any advice would be great. ;-)
Best regards,
Stefan
