Hello, I am in the process of limiting the cached area in mapcache. I am having trouble with both the restricted_extent and ruleset parameters. I first started by using restricted_extent such as "<grid restricted_extent="435567 98889 568247 259687">LyonCC</grid>". That parameter seemed to work. However mapcache returned 404 errors for any tiles outside of the restricted extent. Next I tried to use rulesets instead. The rulesets seem to have no effect, and new tiles were getting generated outside of the visibility extent.
Question 1: When we use restricted extents on a grid should MapCache return a transparent tile, white tile, or a 404 error? Can we control what it returns? Question 2: Do I have my ruleset configured appropriately? <tileset name="LyonBaseMap"> <grid ruleset="CountyBuffer">LyonCC</grid> </tileset> <ruleset name="CountyBuffer"> <rule zoom_level="1 2 3 4 5 6 7 8 9 10 11"><!-Do I need to include zoom levels?--> <visibility> <extent>435567 98889 568247 259687</extent> </visibility> </rule> </ruleset> Thank You! Sincerely, Mark Volz, GISP
