Question on URI Query Strings

[eluser]sophistry[/eluser]
i assume that you mean "query contains two GET variables" not "2 query strings in your URL"

i can see what you are talking about... 1st URL triggers 404, but second doesn't and the REQUEST superglobal holds two keys.

_done (yes, _done with an underscore and not a dot - bizarre)
and
a.

query strings are FALSE and the URL populates _REQUEST, but not _GET ...

could this be related to the mysterious and intermittent "dots turn into underscores" problem?
