-----------------------------------------
Assignee: Daan Hoogland
> Make "mode http" & "option httpclose" in HAproxy.conf configurable on port 80
> -----------------------------------------------------------------------------
>
> Key: CLOUDSTACK-4328
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4328
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router
> Affects Versions: 4.2.0
> Reporter: Roeland Kuipers
> Assignee: Daan Hoogland

> By default CS configures "mode http" & "option http" when it detects a rule
> on public port 80.
> In most situations this is perfectly OK, but we hit a specific situation
> where this has negative impact on performance. In this case a Varnish
> implementation which needs to run on port 80 and cannot run on an alternative
> port. We could imagine this could be an issue for other CS users too.
> Besides this also the maxconnections needs to be raised but this has already
> been address by CS-2997, which is also the inspiration to make the "http
> mode" configurable.
> Details on the performance difference below.
> So we like to see this "http mode"on port 80 configurable. e.g. httpmode
> false-true on the API
> See also CS-2997 and the following commits:
