+== NAME
+
+nng_http_server_hold - get and hold HTTP server instance
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+#include <nng/supplemental/http/http.h>
+
+int nng_http_server_hold(nng_http_server **serverp, const nng_url *url);
+-----------
+
+== DESCRIPTION
+
+The `nng_http_server_hold()` acquires an instance of an HTTP server suitable
+for use in serving the URL identified by _url_, and stores a pointer to it
+at the location pointed to by _serverp_.
+
+This function first looks to see if an existing HTTP server instance exists,
+that is suitable for this. If so, it increments the reference count on it
+and uses that. Otherwise, it will attempt to create a new server instance
+with an initial reference count of one (1).
+
+The server instance is not started, and can have additional configuration
+applied to it before it is later started with
+<<nng_http_server_start#,nng_http_server_start(3)>>.
+
+NOTE: The URL matching logic in determining servers is unable to distinguish
+between different aliases for the same local IP address. This may create
+problems when using URLs for virtual hosting. It is recommended to use
+canonical IP addresses or names in the _url_ to avoid confusion.
+
+== RETURN VALUES
+
+This function returns 0 on success, and non-zero otherwise.
+
+== ERRORS
+
+`NNG_ENOMEM`:: Insufficient free memory exists.
+`NNG_ENOTSUP`:: HTTP not supported.
