WMS capabilities from file?

[Allan Doyle]

Bart,

Try this:

 1. Set up your configuration the way you want it.

 2. Request a Capabilities from the WMS

 3. Put that file on your web server in such a way that it is at a
different URL but that the URL still looks like a Capabilities URL.

 4. Advertise that new URL.

All subsequent access to that URL is by file access, but it will
contain the proper GET addressing so that clients will be able to
access the WMS

Alternate version of this:

 1. Repeat 1-3

 2. Set up an httpd rewrite rule that catches the Capabilities URL and
redirects it to the file based one. This way any clients that are not
able to access the GetMap from a different address than the
GetCapabilities will still work. (This method makes it easier to catch
variations on the request. You can use a regular expression that
matches GetCapabilities but ignores other things)

Then you can set up a cron job to update the static file using wget or
curl periodically.
