Problems connecting to SSL servers. + + It took a very long time before I could sort out why curl had problems + to connect to certain SSL servers when using SSLeay or OpenSSL v0.9+. + The error sometimes showed up similar to: + + 16570:error:1407D071:SSL routines:SSL2_READ:bad mac decode:s2_pkt.c:233: + + It turned out to be because many older SSL servers don't deal with SSLv3 + requests properly. To correct this problem, tell curl to select SSLv2 from + the command line (-2/--sslv2). + + I have also seen examples where the remote server didn't like the SSLv2 + request and instead you had to force curl to use SSLv3 with -3/--sslv3. + +2. Does curl support resume? + + Yes. Both ways on FTP, download ways on HTTP. + +3. Is libcurl thread safe? + + Yes, as far as curl's own code goes. It does use system calls that often + aren't thread safe in most environments, such as gethostbyname(). + + I am very interested in once and for all getting some kind of report or + README file from those who have used libcurl in a threaded environment, + since I haven't and I get this question more and more frequently! |
