<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Question 2: Do I have my ruleset configured appropriately?<o:p></o:p></p>
