I have a rather large list of interesting tags, and when i try to use a Greasemonkey extension (forget what it is) to view all of my interesting tags at once, i get an HTTP 400 request error invalid. So, what exactly is the limit for queries such as those?

Edit: this is the extension.

    Given that it may well be specific to the Greasemonkey extension in question, I suggest you find out which one it is.

    If the problem comes from that script, why not just ask the person who wrote the script?

There are two syntaxes:


and this:


The latter seems to be more tolerant of long URLs.

(and for completeness, there is also a synonym of the first, like so:)


  • it uses the first syntax. I'll see if i can edit the script to do it the other way and see if it helps though.
