[mapserver-users] Mapcache disk cache gives unexpected paths to tiles

[Trygve Aspenes]

Ah, thanks Thomas!

I did not catch that from the documentation.
I also needed to add layout like this:

     <cache name="disk" type="disk" layout="template">
         
<template>/mapcache/{tileset}/{grid}/{dim:time}/{z}/{x}/{y}.{ext}</template>
     </cache>

to make it work ( both from testing and looking at the documentation)

If you use the default this will be like tilecache as far as I 
understand.

Do you have any idea what will be the fastest? To use default like:
     <cache name="disk2" type="disk">
         <base>/mapcache</base>
     </cache>

or the solution above with template? ( As a lot of 000 directories will 
be created with the base one)
