I've been reading the cookie related codes in libcurl. And it seems that there are no libcurl APIs to delete expired cookies.
CURLOPT_COOKIEFILE option just reads in those linked cookie files without checking expire time. CURLOPT_COOKIEJAR option writes out all cookies without checking expire time. It seems that expire time is checked only when libcurl selects outgoing cookies during the sending of a HTTP response. As mentioned above, all expired persistant cookies will be stored in the CURLOPT_COOKIEJAR file even there are useless and invalid. It seems that this file will get bigger and bigger. So will this become a problem? Thanks, With BR xixi
