cdms2 cannot open files if xml generated by cdscan contains different base urls

[cchriste]

Create cdat xml using cdscan -x outfile.xml -f filelist.txt where filelist.txt contains more than one base url, for example:

http://opendap.nccs.nasa.gov:9090/dods/OSSE/G5NR/Ganymed/7km/0.0625_deg/inst/inst30mn_3d_W_Nv
http://opendap.nccs.nasa.gov:80/dods/OSSE/G5NR/Ganymed/7km/0.0625_deg/inst/inst30mn_3d_V_Nv

(note the different port in the two urls)

Results are the same as in #1368: trying to read the actual data fails unable to open the file:

@cchriste The port 9090 is now closed at NCCS. Do you have another example where you want to aggregate 2 files with 2 different URL?

[dnadeau4]

I tried with 2 different URL both at NCCS and it worked. I think the problem happened when NCCS was transitioning between port 9090 and port 80 with their opendap server.

@dnadeau4 did you take a look at #1368 ?

[dnadeau4]

I just did and got a fix for it.
