[THREDDS #DBM-443174]: NetcdfSubset service not working with non-standard THREDDS paths

Hi Kevin,

The NCSS HTML form action URL was hardcoded to start with "/thredds". I've 
checked in a fix to instead use the actual context path of the server (see [1] 
for steps necessary for changing the TDS context path).

This fix will be included in our next release (TDS 4.2.6). There are a few more 
bugs I'm tracking down so 4.2.6 probably won't be out till at least early next 
week.

Also, there are a few links on this HTML form page that will be a bit trickier 
to un-hardcode the use of "/thredds" (a title, a .css file, and a .gif file). 
I've added this to our ToDo list.

Thanks for reporting.

Ethan
