Single sign-on method in multi-application framework

In a client-server architecture, a method comprising:

• receiving at a framework server device a request from a browser via a load balancer, said load balancer decrypting said request and including digital sign-on credentials;
• sending an encrypted response from said framework server device configured to generate a number of application Iframes and a connection between said framework server device and a browser;
• providing a proxy server device and one or more application server devices comprising a plurality of non-interfaced, independent web-based applications;
• receiving at the proxy server device, a request from a URL within one or more of said Iframes via said load balancer;
• storing on the proxy server device a pointer associating first sign-on credentials, for a first of the plurality of web-based applications on at least one application server device, with second sign-on credentials, for one or more second of the plurality of web-based applications on said at least one application server device, in a single framework;
• receiving at the proxy server device the second sign-on credentials in a single response;
• automatically causing, via the second sign-on credentials added in a single request from the proxy server device, sign-on to the first of the plurality of web-based applications through the proxy server device, and immediate tandem display of corresponding secure application information as a consequence of the single request from the proxy server device comprising the first sign-on credentials, and the authenticating of the second sign-on credentials of at least one of the one or more second of the web-based applications, using the pointer;
• causing an indirect communicative connection between the browser and said appropriate application devices through said proxy server device;
• and
• causing content from said appropriate application server devices to be supplied to said proxy server device, wherein said content is further supplied to said browser.
