I was also able to get a second thredds web app (4.3.15) running under a
different URI using the two steps from Ethan and setting service base as John
noted. Unlike John, I wanted a separate content/thredds-test folder so I could
have separate configurations/catalogs. Everything seems to be working so far,
but I noticed when browsing the catalog through a web interface the folder
icons have broken links. The regular thredds install calls
'/thredds/folder.gif' but the second one calls '/thredds-test/' without the
folder.gif part. Equally minor, but when running a second TDS install, you need
to set serverInformation>logoUrl in the threddsConfig.xml. I'm not going to
lose much sleep over broken icons…
Thanks
