Abstract

An information processing apparatus according to this invention, being capable of communicating with a Web server via a network, receives from the Web server a response to a processing request issued to a Web application of the Web server. The information processing apparatus changes, when screen control information described in a header of the response contains information which designates priority of a screen display by a Web browser of the information processing apparatus, priority of the screen display by the Web browser to the designated priority. When an event to display a screen other than a screen by the Web browser occurs while the Web browser presents a screen display corresponding to the response, the information processing apparatus inhibits an interrupt display by the event in order for the designated priority.

Claims

1. An information processing apparatus capable of communicating with a Web server via a network, comprising:

a reception unit that receives, from the Web server, a response to a processing request issued to a Web application of the Web server;

an analysis unit that analyzes screen control information described in a header of the response received by said reception unit;

a change unit that, when the screen control information contains information which designates priority of a screen display by a Web browser of the information processing apparatus, changes priority of the screen display by the Web browser to the designated priority; and

a display control unit that, when an event to display a screen other than a screen by the Web browser occurs while the Web browser presents a screen display corresponding to the response, and when priority of a screen display by the event is lower than the priority of the screen display by the Web browser that has been changed by said change unit, inhibits an interrupt display by the event.

2. The apparatus according to claim 1, wherein when the screen control information contains information which designates priority of a screen display by the Web browser, said change unit changes priority of a screen display set for the Web browser itself to the designated priority.

3. The apparatus according to claim 1, wherein when the screen control information contains information which designates the priority and a storage address in the Web server where display data whose priority is to be changed is stored, said change unit changes, to the designated priority, priority of a screen display corresponding to the display data by the Web browser.

4. The apparatus according to claim 1, wherein the response to the processing request contains display data to be displayed by the Web browser.

5. The apparatus according to claim 1, further comprising a cancel unit that cancels designation of the priority when transition of a screen by the Web browser is detected after said change unit changes the priority of the screen display by the Web browser.

6. An information processing system comprising a Web server and an information processing apparatus capable of communicating with said Web server via a network,

said Web server including:

an execution unit that executes processing corresponding to a processing request from said information processing apparatus;

an attaching unit that attaches, to a header of a response containing a result of the processing executed by said execution unit, screen control information for controlling a display screen of a Web browser of said information processing apparatus, the screen control information containing information which designates priority of a screen display by the Web browser; and

a transmission unit that transmits, to said information processing apparatus, the response to which said attaching unit attaches the screen control information, and

said information processing apparatus including;

a reception unit that receives the response transmitted by said transmission unit;

an analysis unit that analyzes the screen control information described in the header of the response received by said reception unit;

a change unit that changes priority of the screen display by the Web browser in accordance with the information of the priority contained in the screen control information; and

a display control unit that, when an event to display a screen other than a screen by the Web browser occurs while the Web browser presents a screen display corresponding to the response, and when priority of a screen display by the event is lower than the priority of the screen display by the Web browser that has been changed by said change unit, inhibits an interrupt display by the event.

7. A method for controlling an information processing apparatus capable of communicating with a Web server via a network, comprising:

causing a reception unit of the information processing apparatus to receive, from the Web server, a response to a processing request issued to a Web application of the Web server;

causing an analysis unit of the information processing apparatus to analyze screen control information described in a header of the response received by the reception unit;

causing a change unit of the information processing apparatus to, when the screen control information contains information which designates priority of a screen display by a Web browser of the information processing apparatus, change priority of the screen display by the Web browser to the designated priority; and

causing a display control unit of the information processing apparatus to, when an event to display a screen other than a screen by the Web browser occurs while the Web browser presents a screen display corresponding to the response, and when priority of a screen display by the event is lower than the priority of the screen display by the Web browser that has been changed by the change unit, inhibit an interrupt display by the event.

8. A computer-readable storage medium which stores a program for causing a computer to function as an information processing apparatus capable of communicating with a Web server via a network, the program causing the computer to function as:

a reception unit that receives, from the Web server, a response to a processing request issued to a Web application of the Web server,

an analysis unit that analyzes screen control information described in a header of the response received by said reception unit,

a change unit that, when the screen control information contains information which designates priority of a screen display by a Web browser of the information processing apparatus, changes priority of the screen display by the Web browser to the designated priority, and

a display control unit that, when an event to display a screen other than a screen by the Web browser occurs while the Web browser presents a screen display corresponding to the response, and when priority of a screen display by the event is lower than the priority of the screen display by the Web browser that has been changed by said change unit, inhibits an interrupt display by the event.
