RE: stickysession and BalancerMember route

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Thanks - I found that 64 limit in code, and did not look like any other character in the route string match would be problematic but for a route value like route=ab-8080-cde1 we are finding that stickiness is not consistent... the preamble to the route is another string like WebAppName.ab-8080-cde1 but in all cases the separator character is present...and the client is being sent and presenting the stickiness cookie as expected.

When we modify the route to be simple like route=a80801 the stickiness works as expected.

I'll keep debugging.

Thanks.

Rob

The route is limited to 64 characters and must be preceded by a special character within the URL/cookie value (default character is '.', though stickysessionsep= might be used to change it). These are the only constraints I'm aware of..

But this means that the backend must set routed URLs/cookies of that form, otherwise some "automatic" routing can be performed like in https://httpd.apache.org/docs/2.4/en/mod/mod_proxy_balancer.html#example
(the one using mod_headers).
