Hi, do you know of any examples of parsing parameters in header field
values that you can suggest to me? e.g. matching charset=UTF-8 in
"Content-Type: ...; charset=UTF-8" or rel=duplicate in "Link: <...>;
rel=duplicate"
Also can you suggest any examples of checking if a given URL already
exists in the cache or not?
I am attempting a plugin [1] to take advantage of Metalink [2] to
redirect clients to mirrors that already exist in the cache. I am trying
to loop over RFC 6249 "Link: <...>; rel=duplicate" headers and check if
the URL already exists in the cache
