Purpose

The HttpRequest object is a keyed shelf that contains information that can be sent to an HTTP server.

Usage Notes

You create the HttpRequest shelf by using HttpRequestSetFromUrl. A call to this function will create the necessary items for most uses. To use httpRequest components in your program, you must also include the following include statement in your program:

     include "omhttp.xin"

• "last-error" -- a string describing any errors encountered during the last function call. If no errors were detected, it is a zero-length string.
• "host" -- the IP address of the host. This value must be a valid IP address.
• "port" -- the HTTP server port number. This must be a string representation of a valid port number. The default value is "80".
• "proxy-host" -- the IP address of the proxy host. This value must be a valid IP address.
• "proxy-port" -- the HTTP proxy server port number. This must be a string representation of a valid port number. The default value is "80".
• "method" -- the HTTP request method. The default value is "GET".
• "path" -- the path and filename of the resource on the HTTP server to access. The path must begin with the "/" character, which is the default value.
• "http-version" -- the version of HTTP used to format the message. The default value is "HTTP/1.0".
• "cookie-version" -- the version of cookie support. The default value is "1".
• "entity-body" -- additional information to send to the server. The default value is a zero-length string.

Example

Within your program, you can create as many instances of the httpRequest OMX component as you require by declaring global and local variables of type "httpRequest".

  ; HttpRequestSend 

  local HttpRequest my-Request
  local HttpResponse get-Response

  HttpRequestSetFromUrl my-Request
     from "http://www.omnimark.com/whats-new.html"

  HttpRequestSend my-Request into get-Response timeout 60000

  output get-Response{"entity-body"}
