location ^~ modifier

[B.R.]

Hello,

I got kind of a newbie question:
Does the ^~ location modifier finds a matching string at the start of an
URI?

I naively thought it was just a variant of the classic prefix search,
without any constraint on the placement of the matched string in an URI.

Is there a simple way of matching the longest prefix location anywhere in
an URI, discarding any regex location at the same level?

​Thanks,​
