Default handler for OPeNDAP info requests. Returns an html document
describing the contents of the servers datasets.
The "INFOcache" <init-param> element in the web.xml file
specifies the designated location for:
- ".info" response override files.
- Server specific HTML* files.
- Dataset specific HTML* files .
The server specific HTML* files must be named #servlet#.html
where #servlet# is the name of the servlet that is running as
the OPeNDAP server in question. This name is determined at run time
by using the class called Class ( this.getClass().getName() ).
In the C++ code the analogy is the per-cgi file names.
The dataset specific HTML* files are located by catenating `.html'
to #name#, where #name# is the name of the dataset. If the filename part
of #name# is of the form [A-Za-z]+[0-9]*.* then this function also looks
for a file whose name is [A-Za-z].html For example, if #name# is
.../data/fnoc1.nc this function first looks for .../data/fnoc1.nc.html.
However, if that does not exist it will look for .../data/fnoc.html. This
allows one `per-dataset' file to be used for a collection of files with
the same root name.
NB: An HTML* file contains HTML without the , or tags
(my own notation).
Look for the user supplied Server- and dataset-specific HTML* documents.
