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

[TC Haddad]

I’ve had success setting a mask at the Mapserver level, and MapCache has
not problem only rendering imagery to the edge of whatever irregular shape
you need to use (e.g. watershed or county boundary). So maybe try that?

However It’s true, MapCache will still return blank tiles outside the mask
area.

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

[Lime, Steve D (MNIT)]

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!


You can set the

empty_img

To return a blank tile.  I believe the status is still 404 - I don't think you 
can control this

 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?

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

[Mark Volz]

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!
