If \fIproxy\fR is \s-1NULL,\s0 take any default value from the \f(CW\*(C`http_proxy\*(C'\fR environment variable, or from \f(CW\*(C`https_proxy\*(C'\fR if \fIuse_ssl\fR is nonzero. If this still does not yield a proxy hostname, take any further default value from the \f(CW\*(C`HTTP_PROXY\*(C'\fR environment variable, or from \f(CW\*(C`HTTPS_PROXY\*(C'\fR if \fIuse_ssl\fR is nonzero. If \fIno_proxy\fR is \s-1NULL,\s0 take any default exclusion value from the \f(CW\*(C`no_proxy\*(C'\fR environment variable, or else from \f(CW\*(C`NO_PROXY\*(C'\fR. Return the determined proxy hostname unless the exclusion contains \fIserver\fR. Otherwise return \s-1NULL.\s0 .PP \&\fBOSSL_parse_url()\fR parses its input string \fIurl\fR as a \s-1URL\s0 of the form \&\f(CW\*(C`[scheme://][userinfo@]host[:port][/path][?query][#fragment]\*(C'\fR and splits it up into scheme, userinfo, host, port, path, query, and fragment components. The host (or server) component may be a \s-1DNS\s0 name or an \s-1IP\s0 address where IPv6 addresses should be enclosed in square brackets \f(CW\*(C`[\*(C'\fR and \f(CW\*(C`]\*(C'\fR. The port component is optional and defaults to \f(CW0\fR. If given, it must be in decimal form. If the \fIpport_num\fR argument is not \s-1NULL\s0 the integer value of the port number is assigned to \fI*pport_num\fR on success. The path component is also optional and defaults to \f(CW\*(C`/\*(C'\fR. Each non-NULL result pointer argument \fIpscheme\fR, \fIpuser\fR, \fIphost\fR, \fIpport\fR, \&\fIppath\fR, \fIpquery\fR, and \fIpfrag\fR, is assigned the respective url component. On success, they are guaranteed to contain non-NULL string pointers, else \s-1NULL.\s0 It is the reponsibility of the caller to free them using \fBOPENSSL_free\fR\|(3). If \fIpquery\fR is \s-1NULL,\s0 any given query component is handled as part of the path. A string returned via \fI*ppath\fR is guaranteed to begin with a \f(CW\*(C`/\*(C'\fR character. For absent scheme, userinfo, port, query, and fragment components an empty string is provided. .PP \&\fBOSSL_HTTP_parse_url()\fR is a special form of \fBOSSL_parse_url()\fR where the scheme, if given, must be \f(CW\*(C`http\*(C'\fR or \f(CW\*(C`https\*(C'\fR. If \fIpssl\fR is not \s-1NULL,\s0 \fI*pssl\fR is assigned 1 in case parsing was successful and the scheme is \f(CW\*(C`https\*(C'\fR, else 0. The port component is optional and defaults to \f(CW443\fR if the scheme is \f(CW\*(C`https\*(C'\fR, else \f(CW80\fR. Note that relative paths must be given with a leading \f(CW\*(C`/\*(C'\fR, otherwise the first path element is interpreted as the hostname. .PP Calling the deprecated function OCSP_parse_url(url, host, port, path, ssl) is equivalent to OSSL_HTTP_parse_url(url, ssl, \s-1NULL,\s0 host, port, \s-1NULL,\s0 path, \s-1NULL, NULL\s0). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_HTTP_adapt_proxy()\fR returns \s-1NULL\s0 if no proxy is to be used, otherwise a constant proxy hostname string, which is either the proxy name handed in or an environment variable value. .PP \&\fBOSSL_parse_url()\fR, \fBOSSL_HTTP_parse_url()\fR, and \fBOCSP_parse_url()\fR return 1 on success, 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBOSSL_HTTP_transfer\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBOSSL_HTTP_adapt_proxy()\fR, \&\fBOSSL_parse_url()\fR and \fBOSSL_HTTP_parse_url()\fR were added in OpenSSL 3.0. \&\fBOCSP_parse_url()\fR was deprecated in OpenSSL 3.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2019\-2021 The OpenSSL Project Authors.
