HTTP Control Protocol

• Password Check
  When the first time user use browser connect to LT200, LT200 will ask password. LT200 will send login.htm to user. If the password is error, LT200 will send pw_err.htm. If password is okay, LT200 will send pw_ok.htm. You can modify those three HTML file to what you want. LT200 only remember the last IP address user login. Any connection from other IP will be asked for password again.
• Tag Replace
  In the main page, it should display the input status. So, we support some tags that will be replace with other message. The tag we support are

  Tag	Description
  ~get_version~	Get LT200 firmware version.
  ~get_inputX~	X is 1~8. LT200 will replace those tags with "ON"/"OFF" depend on input status.
  ~get_icntX~	X is 1~8. LT200 will replace those tags with number depend on input counter.

  You can see default.htm to get more information.

We use URL link as command to instead of form. The special URL we support as commands are:

Command	Description
set_icntX=Y	X=1~8,Y=0/1. Set input status counter.
set_outputX=Y	X=1~8,Y=0/1. Set output to ON or OFF.

You can view default.htm to get real example. When LT200 receive the HTTP commands, it will send default.htm again. The default.htm will show the status of LT200 because ~get_inputX~ and ~get_icntX~ are replaced. You can see HTTPD.C of DSOCK_AP project to get more detail.
