[mapserver-users] mapcache: restricted extent and ruleset to limit cache area seems ineffective

[Mark Volz]

Steve,
Mapcache is unexpectedly generating and returning a new air photo image outside of the visibility extent.  

Thank You!
Sincerely,
Mark Volz

Is it returning a blank tile? If so that might be expected. I thought mapcache would return a blank tile for requests outside the grid extent.

Hello,

I am still having issues restricting the extent in my mapcache area using rulesets.  I created a rule for all of my zoom levels that has a limited visibility extent.  However, Mapcache is still returning imagery for the entire grid area even though I created a rule that should only display a limited extent.  I am still not sure why the visibility extent rule seems ineffective.

Thanks!
