Hi, I'm hoping John or someone else can answer this.
I'm trying to get my old urls to look as much alike as possible as
before when using aggregation in the catalog file, and migrating from
the 0.6 xml-standard to 1.0.1. (thredds 2.0b to 3.6)
My old service-tag looked like this:
<service name="TOPAZ" serviceType="OpenDAP"
which made the url look like this:
Since url = service.base + dataset.urlPath, I would have expected that the
url would have to start with
so i guess the service you are showing is the internal server base.
My new xml-file I today noticed makes a url like this(not online yet):
(notice the 'topaz')
The service tag that makes such links look like this:
<service name="TOPAZ" serviceType="OpenDAP" base="/thredds/dodsC/">
In the TDS case, the url has to start with /thredds/dodsC/, so that the right servlet gets called. Then the datasetRoot.path gets stuck in there, so that we can find the datasetRoot and map to its location. So the url has to start with
then comes the rest of the filename, presumably
if you want to match
the problem is that theres no dataset root path, so no way to map to the root.
So I guess the answer is no, theres no way to reproduce that url, sorry.
If your three tries ("", "/", ".") don't work, I suspect the TDS does
not support the type of URL you are trying to recreate. The path
basically is an ID for mapping a URL to a datasetRoot or datasetScan.
The idea of an empty path (kind of a default datasetRoot) didn't come
up. I don't think there is a reason it couldn't be implemented. However,
I do know there are lots of places in the code that make sure the path
doesn't start with a slash ("/") and others that assume it is a
I've tried setting the path to "", "/" and ".", but none of them work.
Should I consider this a lost case, or is there some way to get the
old url back?
Unfortunately, I don't know of a mod_rewrite equivalent in the servlet
