Captive portal redirection using display layout information
View Patent ↗According to one embodiment of the invention, a method for controlling access to a network by a network device comprises returning a message prompting connectivity to a captive portal that is different from a HTTP Source Code redirect. The message is an HTML document such as a frameset.
1. A computer-implemented method, comprising:
receiving, by a network device, a request message requesting access to a network resource, wherein the request message originates from a client device utilizing a browser window;
determining that the request message is from a non-authenticated client device;
generating a response message, wherein the response message includes an HTML frameset that specifies display layout information for the browser window, and wherein the display layout information includes a prompt to the client device to access a captive portal when retrieving content to populate the browser window; and
returning the response message to the non-authenticated client device, wherein the response message facilitates displaying a hypertext link to the captive portal in the browser window of the client device, and wherein the HTML frameset in the response message facilitates connectivity between the non-authenticated client device and the captive portal, and wherein returning the response message is performed without reliance on a Hypertext Transfer Protocol (HTTP) Status Code redirect.
2. The computer-implemented method of claim 1 , wherein the network device is an access point that is to provide a transparent HTTP proxy.
3. The computer-implemented method of claim 1 , wherein the network device is an access point, and wherein the HTML frameset includes a media access control (MAC) address of the access point, a name of the access point, or a service set identifier (SSID) of the access point.
4. The computer-implemented method of claim 1 ,
wherein the request message is a Hypertext Transfer Protocol (HTTP) Request message.
5. The computer-implemented method of claim 4 , wherein the HTTP Request message is a HTTP GET Request message.
6. The computer-implemented method of claim 4 , wherein the HTTP Request message is a HTTP POST Request message.
7. The computer-implemented method of claim 1 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the captive portal.
8. The computer-implemented method of claim 1 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the network resource.
9. A computer-implemented system, the system comprising:
one or more processors;
a display;
an input device; and
one or more non-transitory computer-readable storage mediums containing instructions to cause the one or more processors to:
receive a request message requesting access to a network resource, wherein the request message originates from a client device utilizing a browser window;
determine that the request message is from a non-authenticated client device;
generate a response message, wherein the response message includes an HTML frameset that specifies display layout information for the browser window, and wherein the display layout information includes a prompt to the client device to access a captive portal when retrieving content to populate the browser window; and
return the response message to the non-authenticated client device, wherein the response message facilitates displaying a hypertext link to the captive portal in the browser window of the client device, and wherein the HTML frameset in the response message facilitates connectivity between the non-authenticated client device and the captive portal, and wherein returning the response message is performed without reliance on a Hypertext Transfer Protocol (HTTP) Status Code redirect.
10. The computer-implemented system of claim 9 , wherein the request message is received by an access point that is to provide a transparent HTTP proxy.
11. The computer-implemented system of claim 9 , wherein the request message is received by an access point, and wherein the HTML frameset includes a media access control (MAC) address of the access point, a name of the access point, or a service set identifier (SSID) of the access point.
12. The computer-implemented system of claim 9 , wherein the request message is a Hypertext Transfer Protocol (HTTP) Request message.
13. The computer-implemented system of claim 12 , wherein the HTTP Request message is a HTTP GET Request message.
14. The computer-implemented system of claim 12 , wherein the HTTP Request message is a HTTP POST Request message.
15. The computer-implemented system of claim 9 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the captive portal.
16. The computer-implemented system of claim 9 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the network resource.
17. A non-transitory machine-readable storage medium, on which is stored instructions to cause a data processing apparatus to:
receive a request message requesting access to a network resource, wherein the request message originates from a client device utilizing a browser window;
determine that the request message is from a non-authenticated client device;
generate a response message, wherein the response message includes an HTML frameset that specifies display layout information for the browser window, and wherein the display layout information includes a prompt to the client device to access a captive portal when retrieving content to populate the browser window; and
return the response message to the non-authenticated client device, wherein the response message facilitates displaying a hypertext link to the captive portal in the browse window of the client device, and wherein the HTML frameset in the response message facilitates connectivity between the non-authenticated client device and the captive portal, and wherein returning the response message is performed without reliance on a Hypertext Transfer Protocol (HTTP) Status Code redirect.
18. The non-transitory machine-readable storage medium of claim 17 , wherein the network device is an access point that is to provide a transparent HTTP proxy.
19. The non-transitory machine-readable storage medium of claim 17 , wherein the network device is an access point, and wherein the HTML frameset includes a media access control (MAC) address of the access point, a name of the access point, or a service set identifier (SSID) of the access point.
20. The non-transitory machine-readable storage medium of claim 17 , wherein the request message is a Hypertext Transfer Protocol (HTTP) Request message.
21. The non-transitory machine-readable storage medium of claim 20 , wherein the HTTP Request message is a HTTP GET Request message.
22. The non-transitory machine-readable storage medium of claim 20 , wherein the HTTP Request message is a HTTP POST Request message.
23. The non-transitory machine-readable storage medium of claim 17 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the captive portal.
24. The non-transitory machine-readable storage medium of claim 17 , wherein the HTML frameset includes at least one frameset including a frame directed to an absolute Uniform Resource Locator (URL) of the network resource.
