What specific section or headline is this issue about?

last sentence of first paragraph

What information was incorrect, unhelpful, or incomplete?

This line seems wrong: Unlike If-Unmodified-Since, If-Modified-Since can only be used with a GET or HEAD.

What did you expect to see?

One of the 'If-Modified-Since' terms should be 'Last-Modified-Since' for the sentence to make sense. But it isn't clear which one should be changed.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?

The first one says "If-Unmodified-Since". What's confusing?

@jonhelfman I think, there is nothing wrong with the statement. It just making a comparison, and stating the fact that, If-Modified-Since can only be used with a GET or HEADmethod.
Read this.

It seems to be comparing A with A, which doesn't make sense. The expectation is that A would be compared with B, right?

OK. Nevermind. I realize now that I was misreading the text. My bad. Sorry for the problem.
