[webservices] data select no data 404

[Bruce Weertman]

Philip:

There's a few problems here.

(1)  start = 2011-08-23T17.50.00 and end = 2010-02-27T17.60.00
start time is after the end time. I wouldn't expect to get much data  
for that (although you never know).

(2) I'm wondering if the web service should have returned a 400 (Bad  
Request)  instead of a 404 (No Data).

(3) If you swap start and end you'll still get an error:

HTTP Error 400: Bad Request
The dataselect webservice was unable to understand your request: too  
many days requested. greater than 31: 541

If you need that much data, try ws-bulkdataselect, although I'm not  
guaranteeing that will work; it may timeout.

Long time ranges tend to cause timeouts since the underlying data  
retrieval mechanism tends to take so long
before it starts to deliver data. If you do run into problems with  
retrieving long time segments, consider breaking
the request into smaller pieces.

Cheers,
-Bruce
