Greetings Roy!
Thank you for your report! We had a user contact us last week thorough our
support channel who was having an issue with OPeNDAP requests not working,
due to [ and ], much like you report. This user found the following tweak
to Tomcat's server.xml that fixed the problem (specifically, the
relaxedQueryChars attribute):
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" relaxedQueryChars="[]" />
The initial thought was that this was something particular to their server,
but I think your correct in that it's a change in how tomcat handles these
characters. The user who emailed us didn't include the version of Tomcat
they were using, so I'm not 100% sure, but this sure sounds like the issue.
What I don't know yet is if this must be configured at a level above the
TDS (like tomcat's server.xml), or if this something we could address in
the TDS codebase (in a servlet container agnostic way).
In your case, if you try the request but encode the square brackets by hand
using %5B for '[' and %5D for ']', does the query work?
Thank you again!
Sean
