HTTP Server

RL-TCPnet has integrated a tiny Hypertext Transfer Protocol Server (HTTP) that can be used to transfer integrated web pages to a remote client.

The following HTTP Server options are configurable:

• HTTP Server switch enables or disables the HTTP Server service in your application. It is enabled when this value is set to 1. It should be set to 0 when HTTP server is not used in your application.

  #define HTTP_ENABLE    1
  

• Number of HTTP Sessions specifies the number of available HTTP sessions. You must increase this number if the web page has many objects (like gif or jpeg images). The remote HTTP client, sometimes called the web browser, opens multiple connections when downloading such pages.

  #define HTTP_NUMSESS   3
  

• Port Number specifies the listening TCP port number. The default HTTP server listening port is 80.

  #define HTTP_PORTNUM   80
  

• Server-Id header specifies the custom HTTP Server header identification. This identification is contained in each Web server response packet. When this option contains an empty string, a default Server-Id from the library is used instead. The default definition is an empty string.

  #define HTTP_SRVID     ""
  

• Enable User Authentication switch enables or disables the WEB Server authentication with a username and a password. The user authentication is enabled, when this value is set to 1.

  #define HTTP_ENAUTH    1
  

• Authentication Realm is the string which displays in the internet browser's authentication dialog when authentication is required. This is a zero terminated string.

  #define HTTP_AUTHREALM "Embedded WEB Server"
  

• Authentication Username is the username identification.

  #define HTTP_AUTHUSER  "admin"
  

• Authentication Password is the default password, that must be stored in Non volatile memory. The user can change the password later.

  #define HTTP_AUTHPASSW ""
  

Note

• When the HTTP server is not enabled, the ARM linker does not link the HTTP support modules to your application and thus reduces the code size and memory usage.
