Hi List,
I would ask, if it's possible to use the http protocol to give a reference
location to the shape files in the URL definition of the coverage dataset
editor. For a special map I will use the http protocol not the file path
open. Normaly I write file:path/to/my/shape/files but now I will use
http://path/to/my/shape/files
Is it possible to do with the coverage service of geoserver?
Thanks a lot,
Cheers Klaus

Ciao Klaus,
I am assuming youa re talking about having the imagemosaic pointing to
a shapefile throuh an http URL.
This is not possible atm.
Simone.

Hi Simone,
right the plan should be to use a shape file from a different server
machine. It's pity that it doesn't work, maybe it would be a nice feature of
the imagemosaic in the feature development.
Thanks for response and have a nice day,
Cheers Klaus

Hum... I'm really wondering how it could be a nice feature. I mean,
due to network delays the performance would be absymal, even with a
fast local network you would completely loose random access, which
is critical to directly reference and eventual inner tiling or
overviews present in the mosaic tiles (it's possible, and actually
recommended to have overviews inside the tiles), or to read the
proper part of the file in case of of a wavelet based compression.
The only case in which you _might_ not loose them is with a protocol
designed for file sharing such as the windows file share or NFS, but
in that case, you can easily mount the remote folders in your
local filesystem (or turn them into an extra unit for windows)
and have the software treat them as local files.
What am I missing?
Cheers
Andrea

Hi Andrea,
all in all you might be right. The only point is the load balancing two
servers behind an apache http server.
This is reason why I've tried to use the http protocol. I have two different
file server as backend for the coverages, but they are not clustered, or
realy save, for example with a heartbeat.
The load balancer would be a good solution for this problem. If one file
server is going down the balancing will give the secound hundret procent and
the backend coverage data support are realy save for my configuration.
Best regards,
Klaus
