<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> 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" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> 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" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> Question 2: Do I have my ruleset configured appropriately?<o:p></o:p></p>
