[mapserver-users] Mapcache Question

[Vladimir]

 Hello ALL!

I dig into MapCache now and my modest comprehension is:
1) MapCache uses Mapserv for seeding tiles or more exactly -
sends WMS request to Mapserv for getting a map:
<source>....</source> section in a mapcache.xml file

2) Ol uses MapCache for rendering that tiles or more exactly -
sends WMS(or other) request to MapCache:
new ol.layer.Tile({ 
source: new ol.source.TileWMS(({
url: 'myhost/mapcache/?',
params: {'LAYERS': 'mytileset'},
serverType: 'mapserver'
}))
})
where
/mapcache/ is path to a mapcache.xml(aliased through Apache),
'mytileset' is <tileset name="mytileset"> section in a mapcache.xml file

3)The Seeding and the rendering needs other configuration of mapcache.xml file(it is needs clarification).

4)The seeding may be through:
mapcache_seed -c mapcache.xml -t mytileset-g mygrid
or 
during a certain map area is requested by client (it is needs clarification).
Thanks for any correction.
Best regards.

>MapCache Is simply a tiling server.  It will take images from a source and store them in a cache.  These tiles are exposed as services to clients - WMTS, WMS, TMS etc...  MapServer on the other hand will read source data (GIS files / database) and render images based on rules defined in the mapfile.  These images are used as the source for MapCache.

Now from what I understand, my mapcache .xml will list out the parameters of the mbtile and then I add a layer within my mapfile referencing the .xml which I should then be able to to use as WMTS using openlayers. I just haven't grasped how mapcache and mapserv work together so any clarification would be helpful. Thanks for your time.
