Isn't the saying "twice is enemy action..."?The alternative, I think, is to change the opendap .html response to use the % encoded form
for '[' and ']' when it constructs requests. WIll ncss have same problem?In any case,I do not know if changing the .html response would cause trouble when using
older versions of tomcat that by default allow []. =Dennis Heimbigner Unidata On 7/30/2018 4:36 PM, Sean Arms wrote:
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!

If I run in Tomcat 8.5.14, using the default TDS settings that are installed if nothing else is there, if I go to: http://localhost:8080/thredds/dodsC/testAll/2004050312_eta_211.nc.html select datetime and asked for ASCII, it works. If I do the exact same thing with Tomcat 8.5.32, I get a blank page. From looking at the Tomcat changelogs, I think there may have been a change at 8.5.15. It appears to be something to do with the handling of '[' and ']'.
