Re: [geowebcache-users] Use of SLD with geowebcache

[Javier de la T. <ja...@gm...>]

Hi,

Well, what I actually want is to have a different SLD document per  
zoomLevel. I know I could tweak this inside the SLD by using the scale  
factors, but this is a headache because of the diffent scales at  
different latitudes... I also need to pass parameters to the SLD to  
further query the featureType in the db.

So what I want is to do something like:

>> http://172.16.178.129:8080/geowebcache/service/gmaps?layers=topp:density&zoom=2&x=0&y=1&sld=http://mySLD 
>> ?zoom=2&mySearch=whatever

The cache will only work for the same zoom level and the same search  
for two users, but this will be a high boost to my application.

At the end what i want is that geowebcache passes this parameter to  
geoserver as it is, and just by looking at the complete url it should  
know that the same request has done before...

Uhmm, I dont know if I am explaining myself...

Javier.
