Yeah that might work. something along the lines of:
curl_easy_getinfo(curl, CURL_INFO_TIMECONDITION, &bool);
if (bool == 1)
/* The time condition was met and therefore the file was downloaded */
/* The time condition was not met and therefore the cached version should be
Again, if you think that's a good solution I'd be glad to work on it.
Regardless though I've attached a minor patch to update the docs. The docs
says that timeconditions only apply to HTTP, that's not true. Libcurl
attempts to get the file's modification time for FTP transfers, and it will
do just like it does with the HTTP Last-Modified header, it will check the
conditions itself. So I've moved the CURLOPT_TIMECONDITION/VALUE to not be
listed under the HTTP section and to also note that it may work for FTP as
well if the modification time can be retrieved.
