In fact, it does open in a browser and the result is "General failure: Invalid Coordinates". This URL runs the PHP script pqs.php, this script needs input coordinates, if there is no coordinates supplied, this script returns the message about invalid coordinates. This message is not a message from your browser, it is not a message from the web server, it is a message from pqs.php. Your browser and the web server are just fine. And frankly speaking, what result are you expecting? pqs.php is a script that returns some data depending on the input data you give. You give no input, you get no output. > https://nationalmap.gov/epqs/ > will. I imagine this may have something > to do with redirects, but who knows. This URL is missing the filename part (after the last /), in that case, the web server uses a default file (depending on the configuration of the web server) and the default file is presenting a page that asks for coordinates. So you are asking 2 differents URL, that corresponds to two different pages, each page giving the correct result. > When I put > https://nationalmap.gov/epqs/pqs.php > into a web browser it says: > General failure: Invalid Coordinates > > > When I put > http://ned.usgs.gov/epqs/pqs.php > into a web browser it says the same exact thing.
