No, like I said, it's probably using older code (with whatever updates they've
been testing) that still accepts a + in the url. The Vizier resource worked
for years. But as they said, "if your program is following properly the HTTP
conventions"- CdC's code doesn't follow this convention, since + should be
coded as %2B (just as you may sometimes see spaces coded as "%20", or tilde
("~") as %7E. Some symbols should not be used in URLs, and CdC violates this
convention.
Of course it's possible if they do use the webviz version of their code on all
their computers in the future, it will work again, even though it technically
violates this convention.
