We have compiled and installed haproxy version 1.6 dev2.
If we use cookie insert all works, but if we use cookie prefix (ASP.NET_SessionId) or sticky table in which one have to specify cookie to be sticked, so using cookie name = ASP.NET_SessionId) we have a strange behavior.
BLOCK1
As you can see below, we open a browser and make a request, cookie prefix mechanism works well, we can login and use the application (all subsequent requests go on the some server).
BLOCK2
But if we open a new browser instance (chrome in this case, but this happen also if we open IE) the client uses a strange "ASP.NET_SessionId" cookie without haproxy prefix with back-end server, server does not ask client to set a new cookie.
As of login, clearly, backend server does not recognize the cookie sent by client (haproxy do a plain roundrobin distribution, no cookie management was done) and so backend server return an error.
Can this be a bug of haproxy or a bad configuration by us ?

If we use cookie insert all works, but if we use cookie prefix (ASP.NET_SessionId) or sticky table in which one have to specify cookie to be sticked, so using cookie name = ASP.NET_SessionId) we have a strange behavior.
BLOCK1
As you can see below, we open a browser and make a request, cookie prefix mechanism works well, we can login and use the application (all subsequent requests go on the some server).
BLOCK2
But if we open a new browser instance (chrome in this case, but this happen also if we open IE) the client uses a strange "ASP.NET_SessionId" cookie without haproxy prefix with back-end server, server does not ask client to set a new cookie.
As of login, clearly, backend server does not recognize the cookie sent by client (haproxy do a plain roundrobin distribution, no cookie management was done) and so backend server return an error.
Can this be a bug of haproxy or a bad configuration by us ?
