[THREDDS #HPI-566023]: Error from TDS for escaped characters in request

["Unidata THREDDS Support" <support-thredds@xxxxxxxxxxxxxxxx>]

Hi Dan,

> I'll ask this question.

What version of the TDS are your running?

> When accessed by a current OPeNDAP client I'm getting an error
> returned because it appears the DAP client is escaping certain
> characters in the constraint.  If I try the same request from a
> browser without the escaped constraint it works fine.  Sooo, my
> question is do you think this problem is resolved in a newer version
> of the TDS, or for that matter is it a TDS problem?

I'm not seeing this problem on our main server (http://motherlode.ucar.edu:8080/thredds/) which is at Version 3.16.15 Build Date = 2007-08-10 00:32:05

I tried it for both a DDS and ascii response (in case it was the ascii part that didn't unencode).

I remember this being a problem but I don't know when it was fixed or whether it was in the TDS or OPeNDAP code. Could have been either though I suspect the TDS is/should be doing the unencoding.
