Header "DESCRIPTION" \fBOSSL_HTTP_adapt_proxy() takes an optional proxy hostname proxy and returns it transformed according to the optional no_proxy parameter, \fIserver, use_ssl, and the applicable environment variable, as follows. If proxy is NULL, take any default value from the \*(C`http_proxy\*(C' environment variable, or from \*(C`https_proxy\*(C' if use_ssl is nonzero. If this still does not yield a proxy hostname, take any further default value from the \*(C`HTTP_PROXY\*(C' environment variable, or from \*(C`HTTPS_PROXY\*(C' if use_ssl is nonzero. If no_proxy is NULL, take any default exclusion value from the \*(C`no_proxy\*(C' environment variable, or else from \*(C`NO_PROXY\*(C'. Return the determined proxy host unless the exclusion value, which is a list of proxy hosts separated by \*(C`,\*(C' and/or whitespace, contains server. Otherwise return NULL. When server is a string delimited by \*(C`[\*(C' and \*(C`]\*(C', which are used for IPv6 addresses, the enclosing \*(C`[\*(C' and \*(C`]\*(C' are stripped prior to comparison.

\fBOSSL_parse_url() parses its input string url as a URL of the form \f(CW\*(C`[scheme://][userinfo@]host[:port][/path][?query][#fragment]\*(C' and splits it up into scheme, userinfo, host, port, path, query, and fragment components. The host (or server) component may be a DNS name or an IP address where IPv6 addresses must be enclosed in square brackets \*(C`[\*(C' and \*(C`]\*(C'. The port component is optional and defaults to 0. If given, it must be in decimal form. If the pport_num argument is not NULL the integer value of the port number is assigned to *pport_num on success. The path component is also optional and defaults to \*(C`/\*(C'. Each non-NULL result pointer argument pscheme, puser, phost, pport, \fIppath, pquery, and pfrag, is assigned the respective url component. Any IPv6 address in *phost is enclosed in \*(C`[\*(C' and \*(C`]\*(C'. On success, they are guaranteed to contain non-NULL string pointers, else NULL. It is the responsibility of the caller to free them using OPENSSL_free\|(3). If pquery is NULL, any given query component is handled as part of the path. A string returned via *ppath is guaranteed to begin with a \*(C`/\*(C' character. For absent scheme, userinfo, port, query, and fragment components an empty string is provided.

\fBOSSL_HTTP_parse_url() is a special form of OSSL_parse_url() where the scheme, if given, must be \*(C`http\*(C' or \*(C`https\*(C'. If pssl is not NULL, *pssl is assigned 1 in case parsing was successful and the scheme is \*(C`https\*(C', else 0. The port component is optional and defaults to 443 if the scheme is \*(C`https\*(C', else 80. Note that relative paths must be given with a leading \*(C`/\*(C', otherwise the first path element is interpreted as the host.

Calling the deprecated function OCSP_parse_url(url, host, port, path, ssl) is equivalent to OSSL_HTTP_parse_url(url, ssl, NULL, host, port, NULL, path, NULL, NULL).

Header "RETURN VALUES" \fBOSSL_HTTP_adapt_proxy() returns NULL 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.

\fBOSSL_parse_url(), OSSL_HTTP_parse_url(), and OCSP_parse_url() return 1 on success, 0 on error.

Header "SEE ALSO" \fBOSSL_HTTP_transfer\|(3) Header "HISTORY" \fBOSSL_HTTP_adapt_proxy(), \fBOSSL_parse_url() and OSSL_HTTP_parse_url() were added in OpenSSL 3.0. \fBOCSP_parse_url() was deprecated in OpenSSL 3.0.
