Wiki Testing/ServerInstallationGuide5

Constructing the URL

After a dataset has been installed, and the handler programs installed, you need to know what its address is. If you've tested the web server installation as in ( Chapter2), you know the beginning of the URLs that will point to data at your site.

(If you're using the DRDS Java server, see ( Section 4.3.3).)

Suppose your web server's document root is at:

/var/www/html/

And you are serving netCDF data that you've stored at:

/var/www/html/datasets/atlantic/cooldata.nc

Following the test URL in ( Chapter2), this would be the URL to use in a client.

http://yourmachine/cgi-bin/nph-dods/datasets/atlantic/cooldata.nc

Note that this URL will work for a DAP client, but not for a standard web browser. If you want to use a standard web browser to test your installation, read on, and also take a look at The OPeNDAP QuickStart Guide . See note

Constructing a OPeNDAP/JGOFS URL

Suppose that you have installed the OPeNDAP/JGOFS handler, as described above, on the machine test.opendap.org. And a partial listing of the the data objects dictionary contained the following definitions:

test0=def(/var/www/html/data/test0.data)
s87_xbt=def(/var/www/html/data/xbt.catalog)
s87_ctd=def(/var/www/html/data/ctd.catalog)
htf=autoedges(/fronts/hatteras-to-florida/edges)
htn=autoedges(/fronts/hatteras-to-nova-scotia/edges)
glk=autoedges(/fronts/great-lakes/edges)

A URL that references the data object 's87_xbt' would look like:

http://test.opendap.org/cgi-bin/nph-dods/s87_xbt
