Hi Nathan,
The HTML view of a catalog isn't defined in the spec. So, the TDS
(and underlying servlet framwork) does not assume that a remote
THREDDS catalog can be requested in an HTML view with a simple
replacement of .xml with .html. Instead it tries to generate the
HTML view itself with the service URL you are seeing.
Thanks Ethan. I figured it was something like that. It raises issues
for my application as I am trying to use the UNIDAT THREDDS code as an
implementation of THREDDS in Hyrax - which is not the TDS so doesn't
have the catalogServices servlet. I guess the reason I am making the
point is that this is another place where the THREDDS core is tightly
wedded to the TDS.

Ethan et al.,
This is a question about THREDDS 3.16 and DataRootHandler.
I am looking at configuring a THREDDS catalog to reference a
catalog on another system. I imagined that I could put this:
<catalogRef xlink:href="http://motherlode.ucar.edu:8080/thredds/catalog.xml
" xlink:type="simple" xlink:title="Motherlode, UNIDATA"
name="Motherlode_UNIDATA"/>
into my catalog.xml.
When I do that and ask the server for the catalog.xml I get this
entry:
<catalogRef xlink:href="http://motherlode.ucar.edu:8080/thredds/catalog.xml
" xlink:title="Motherlode, UNIDATA" name="" />
Although it lost the xlink:type attribute (which is expected) and
also the value of the name attribute (not expected), it should
still work since the the xlink:href attribute is correct, and
dereferencing that absolute URL it will get you that catalog.
However when I ask for the catalog.html I get this bit:
<a href="/opendap/catalogServices?catalog=http://motherlode.ucar.edu:8080/thredds/catalog.xml
"><tt>Motherlode, UNIDATA/</tt></a></td>
Now, in my mind the value href attribute should have been:
http://motherlode.ucar.edu:8080/thredds/catalog.html
I think this because this (the catalog.html document) is the
presentation view of the catalog and it should point to the
presentation view of the referenced catalog. Rather, it points to
a local servlet... Which I am not running :( because I didn't know
about it or what it might do.
Can you explain what's going on?
