Learning/Trying to use Net::Curl with Cookie Jar

YenForYang has asked for the wisdom of the Perl Monks concerning the following question:

I've never used libcurl before, but I wanted to start using it in curl for improved HTTP performance. I've been looking through all the Net::Curl::Easy:: keys, browsing the contents and comparing with curl.haxx.se and noticed that Net::Curl doesn't have a curl_easy_cleanup function.

I'm asking this because on the manual page for CURLOPT_COOKIEJAR, it says

...will make libcurl write all internally known cookies to the specified file when curl_easy_cleanup is called.

So...How does one store cookies in a cookie jar (file) by specifying CURLOPT_COOKIEJAR?

EDIT: To give an idea of what I'm trying to do for now (this case): I'm making a simple GET request pretty much equivalent to this: curl -qsL -b cookies.txt -c cookies.txt <URL> and parse the html response content (html of URL).

I actually just found `curl_easy_cleanup` in this chunk of code from Curl_Easy.xsh: static void perl_curl_easy_delete( pTHX_ perl_curl_easy_t easy ) /{{{/ { / this may trigger a callback, * we want it while easy handle is still alive / curl_easy_setopt( easy->handle, CURLOPT_SHARE, NULL ); / when using multi handle, the connection may stay open in th +at multi, * but the easy will be long dead. In case of ftp for instance +, connection * closing will send a trailer with no apparent destination / / this also disables header callback if not using multi, SORR +Y / curl_easy_setopt( easy->handle, CURLOPT_HEADERFUNCTION, NULL ) +; curl_easy_setopt( easy->handle, CURLOPT_WRITEHEADER, NULL ); if ( easy->handle ) curl_easy_cleanup( easy->handle ); perl_curl_easy_delete_mostly( aTHX_ easy ); if ( easy->share_sv ) sv_2mortal( easy->share_sv ); Safefree( easy ); } /}}}*/ [download] Now I just have to figure out how to call it....

I thought `CURLOPT_COOKIEFILE` was read-only: This option only reads cookies. To make libcurl write cookies to file, see CURLOPT_COOKIEJAR.	[reply] [d/l]
