[MapProxy] 'expires_hours' parameter for the WTMS service ?

[benoit.david at wms.lautre.net]

Hello,

I am testing MapProxy to use it as an tile server optimized on caching.
The 'expires_hours' parameter applies on the TMS service.
Is there a way to define the number of hours a tile is valid for the WTMS
service ?
