[mapserver-users] Adding cache control headers to wms requests

[Stephen Woodbridge]

Hi all,

I need to add the following headers to some wms responses:

|Cache-Control: no-cache, no-store, must-revalidate Pragma: no-cache 
Expires: 0 I am aware that I can set: MAP WEB METADATA ... 
"ows_http_max_age" "0" END END ... END But it seems like it would be a 
good idea to be able to set additional headers also. Maybe something 
like: WEB HEADERS "||Cache-Control: no-cache, no-store, must-revalidate|"
     "|Pragma: no-cache|"
     "Expires: 0"
   END
   METADATA
     ...
   END
END

This would provide an easy way to add arbitrary response header.
The various headers are because browsers are not consistent which headers they respond to.
See||   https://stackoverflow.com/questions/49547/how-do-we-control-web-page-caching-across-all-browsers

Maybe we can already do this and I'm not aware of how. I could write a wrapper around mapserver and
funnel some requests through it to do this, but it would be nice if mapserver via the mapfile can do it.

Thoughts?
