Hi list,
I've run into a problem at an application we have here. I must show a
few layers to the client. Some of them never change and are very slow
to render, so I want to use tile caching. The others are updated every
30 seconds, so tile caching is not recommended.
For i.e., 5 layers (A, B, C, D and E at this order). A, C and E with
tile caching, B and D without.
It seems like I have no way to get them at a single WMS request, and I
don't want to split them at many requests. Have someone had a similar
problem, or have a good idea of how to solve this?
I'm considering implementing a service to plug at GeoServer, that
receives the WMS request (containing all layers), split them to make
the necessary requests to GeoServer and/or GeoWebCache at the server
and combine the answers at a single response. But I'm not sure if
it's the best way to go.
Thanks,
Fabio
It would probably be a good idea to first try and optimize the layers
that you are reporting to be "slow".
Can you give us some more information about them.
Simone.
