  166. \&\fBX509_load_http()\fR and \fBX509_CRL_load_http()\fR loads a certificate or a \s-1CRL,\s0
  167. respectively, in \s-1ASN.1\s0 format using \s-1HTTP\s0 from the given \fBurl\fR.
  168. .PP
  169. If \fBbio\fR is given and \fBrbio\fR is \s-1NULL\s0 then this \s-1BIO\s0 is used instead of an
  170. internal one for connecting, writing the request, and reading the response.
  171. If both \fBbio\fR and \fBrbio\fR are given (which may be memory BIOs, for instance)
  172. then no explicit connection is attempted,
  173. \&\fBbio\fR is used for writing the request, and \fBrbio\fR for reading the response.
  174. .PP
  175. If the \fBtimeout\fR parameter is > 0 this indicates the maximum number of seconds
  176. to wait until the transfer is complete.
  177. A value of 0 enables waiting indefinitely,
  178. while a value < 0 immediately leads to a timeout condition.
  179. .PP
  180. \&\fBX509_http_nbio()\fR and \fBX509_CRL_http_nbio()\fR are macros for backward compatibility
  181. that have the same effect as the functions above but with infinite timeout
  182. and without the possibility to specify custom BIOs.
