What are some nice sources for User-Agent strings?
I'm testing a library that processes queries based on User-Agent. In my tests, I'd like to feed it as much strings as possible.
Where can I find a public collection of User-Agent strings?
I'm mainly interested in "real" strings, but a collection of specifically interesting strings could be of use (like examples that are likely to put stress on parsers). Plain newline-delimited list is OK.
