ts.server_request.server_addr.set_outgoing_addr
-----------------------------------------------
**syntax:** *ts.server_request.server_addr.set_outgoing_addr()*

**context:** earlier than or inside function @ TS_LUA_HOOK_SEND_REQUEST_HDR hook point

**description**: This function can be used to set outgoing socket address for the request to origin.

The ts.server_request.server_addr.set_outgoing_addr function requires three inputs, ip is a string, port and family is number.

Here is an example:

::

function do_global_send_request()
ts.server_request.server_addr.set_outgoing_addr("192.168.231.17", 80, TS_LUA_AF_INET)
end

`TOP <#ts-lua-plugin>`_

ts.server_request.get_url_host
------------------------------
**syntax:** *host = ts.server_request.get_url_host()*
