Re: [mapserver-users] defining fallback source in WMS client definition

2020-03-30 Thread Lars Fricke 

  
  
Hello Jérome,

Thank you for pointing out this option. I will keep it in mind once
we use MapCache one fine day. For now I think having to dive into
that seems too large of a task.

  Dear all,


We use Mapserver 7.4.3 on Ubuntu. We use it as WMS client to
collect several WMS into one place, serving them to our
application.

The task now is to define a fallback for one of the WMS source
servers. That means:


Mapserver will have two technically identical sources for the
same output layer, only the URL is different. Is there a way to
define (in mapfile preferably) that one source is only used if
the other fails (is offline)? I thought of layer groups but then
I will have a duplicate call if both sources are available. I do
know this would be a better task for a load balancer or proxy
but we do not have that option at this time.


Thank you for your time and thoughts.

Hello Andreas,
  
  Thank you for your advice. That sounds like the best way. We are
  on Nginx but I guess it can do the same.

  Hallo Lars,

since you're on Ubuntu you're likely running MapServer in combination with an Apache HTTPd. So one option is to use an URL on localhost in your MapFile and let your webserver fordward it via mod_proxy using a fail over configuration.
