Re: switching backends based on boolean value
If it is http then I'd use a cookie. Apps can decide when to give out that cookie You could use a table and add to the table using socket commands Neil On 17 Apr 2015 05:27, "Dennis Jacobfeuerborn" wrote: > On 17.04.2015 00:51, Igor Cicimov wrote: > > On Fri, Apr 17, 2015 at 3:26 AM, Dennis Jacobfeuerborn < > > denni...@conversis.de> wrote: > > > >> Hi, > >> I'm trying to find the best way to toggle maintenance mode for a site.

I was hoping to avoid this as I also want to switch between the maintenance/live site based on other ACLs e.g. based on the clients IP address or a header. In that case removing the live servers isn't really an option. Regards, Dennis

switching backends based on boolean value
Hi, I'm trying to find the best way to toggle maintenance mode for a site. I have a regular and a maintenance backend defined an I'm using something like: frontend: acl is_maintenance always_false use_backend back-maintenance if is_maintenance default_backend back Since I saw some ACL modifying command for the unix socket I figured that I could use those to switch the acl dynamically but apparently while there are get/add/del/clear commands there is no actual command to set an acl. Is there a way to accomplish this kind of dynamic switching? Regards, Dennis
