HTTP Proxy

HTTP Proxy Device Server plugin allows you to access the embedded Web Servers of Device Servers currently connected to Iotellect Server which are located in private networks or have no static IP addresses. This is done using HTTP.

When Iotellect Server is started, this driver installs a special web application into the Iotellect Server's embedded Web Server. This application turns Iotellect Server into the HTTP proxy server allowing to access web pages contained in the Device Servers connected to it and working through the HTTP Proxy driver.

NEW TERM: A proxy server is software which lets clients make indirect network connections to other network locations. The client connects to the proxy server, requests a connection, file, or other resource available on a different server, and the proxy accesses the resource for the client and relays it to the client.

More information about the HTTP Proxy service may be found under HTTP Proxy Service in the System Basics section.

When the driver is running, the following URLs may be used to access web page provided by the Web Server embedded into the Device Server connected to Iotellect Server:

https://server_address/dev/device_server_owner/device_server_name/page_path/page_name

http://server_address/dev/device_server_owner/device_server_name/page_path/page_name

The first example uses a secure HTTPS connection between the Web Browser and Iotellect Server. The second example shows a non-secure HTTP connection.

server_address is the IP of the Iotellect Server or one of the DNS addresses defined in the Host Name Aliases. If a DNS address is used, it should also be properly configured in DNS (i.e, you also have to configure your DNS server and make sure you can indeed reach the Iotellect Server's IP via this DNS address).

device_server_owner is the name of the user account under which the Device Server is registered

device_server_name is the name of Device Server Account

page_path and page_name should point to the requested page in the Device Server's embedded Web Server.

Example:

https://ls.nuclear-sub.com/dev/admin/thermometer/gui/view_temperature.html

This URL will provide access to the page /gui/view_temperature.html contained in the Web Server embedded into the Device Server admin.thermometer when it is connected to Iotellect Server. It assumes Iotellect Server is accessible via the ls.nuclear-sub.com address. The requested page will be viewed through a secure connection, even if connection between Iotellect Server and Device Server is not secure.

HTTP Internal Server Error (Error 500) is shown by the HTTP Proxy Web Application in the following cases:

  • User specified in the URL does not exist
  • Device Server specified in the URL does not exist
  • Device Server is offline
  • Device Server is not working through the HTTP Proxy driver

See HTTP Proxy Service for more information.
