Abstract
The invention provides a method for keeping an active session in browser/server (BS) architecture portal application. Under the condition of lowering of a BS architecture application session timeout value, a hyper text transport protocol (HTTP) message is regularly transmitted by utilizing an asynchronous script of a browser to simulate a 'heartbeat' request, so that the session overhead of a server is decreased, and the activity of the session is also ensured.
Description
1, technical field
The constructing technology that the present invention is the relevant service management of value-added service and the user serves the WEB door.Especially the method that keeps active sessions in a kind of BS framework portal application.
2, background technology
BS framework door applications exploiting http protocol as the service end logic of managing business, as client, utilizes html document to realize user's operation, browser interface with browser with the WEB application server.
Http protocol is a kind of request formula interaction protocol, and basic interactive mode is:
1) user submits the HTTP access request of visit related pages/resource to through browser.
2) the WEB server receives the HTTP request of browser, and analysis request is also returned desired page/resource.
3) browser is received the http response that the WEB server returns, and resolves HTML content wherein, and carries out the interface and appear.
Http protocol is a stateless protocol, and the function that the session life cycle keeps (like the foundation of session, keep, terminate) is not provided, and these functions are provided by application layer module usually; Peace preservation association's speech phase generally adopts browser Cookie data to combine service end session tracking data to accomplish, and generally is when the user logins the door success, to set up session, termination session when withdrawing from door; Because the stateless character of http protocol, even the user closes browser, its session tracking data still is present in the server.
For guaranteeing session jd, the promptness of keeping; A large amount of session tracking datas generally is directly to deposit in the internal memory of server, for the more portal application of number of users, is peace preservation association's speech phase; Usually to consume a large amount of server memory and/or be used to transmit the network traffics of Cookie data; When situation was serious, the door response was slow, the Business Processing inefficiency; This moment, general solution was that the as far as possible little session timeout time limit is set; Consequently surpass the session in overtime time limit for inoperation of a specified duration; Its status data is removed from service end,, thereby server is freed from the low internal storage state that continues with the memory requirements of reduction service end.Because session timeout must land when relevant user operates once more, to rebulid session once more.
The cost of above-mentioned way is, when the user wouldn't operate, is easy to take place session timeout, at this moment needs the user to re-enter user name/password and lands; Frequent login causes user experience not good.
3, summary of the invention
The objective of the invention is: in the BS framework applications, each login user all can be safeguarded a session state data in the WEB service end, for a large amount of concurrent users' situation; The memory cost that is used for session is very big; And because http protocol is easy to generate invalid session, and can not get removing timely; For guaranteeing the handling property of server; Generally can set an inefficacy timeout value for inactive session, at this moment produced a problem: timeout value is provided with oversize, reclaims the DeGrain of service end memory cost; Be provided with too shortly, session is easy to overtime, needs the user to land again frequently, and user experience is not good.Keep the method for active sessions well to solve the problems referred to above in a kind of BS framework of the present invention portal application.
Technical scheme of the present invention is: adopt the browser of main flow all to support asynchronous script calls technology.For the portal application of using HTML framework interface tech (FrameSet&Frame or IFrame or DIV layer); Hold in the frame page that does not upgrade that within it asynchronous HTTP invoke script being set, and regularly trigger " heartbeat " request through DHTML script timer.For the portal application of not using HTML framework interface tech, can in each related pages, insert above-mentioned asynchronous script.Do not have specific (special) requirements on server end " heartbeat " processing of request, simply return the HTTP success response and get final product browser.
" heartbeat " interactive relation of browser and WEB application server is following, as shown in Figure 1:
1) timer in the browser page regularly triggers, and asks to WEB application server asynchronous transmission " heartbeat ".
2) the WEB server end is accepted " heartbeat " request, upgrades session status, returns " heartbeat " and confirms response.
The transmission frequency of " heartbeat " message should be simulated the frequency of ordinary people's normal running, cannot be shorter than this frequency, in order to avoid cause unnecessary additional networks expense, and increase the weight of the service end load; Should on the basis of artificial average operation frequency, prolong slightly, once be advisable with 5 to 10 minutes.
Utilize the method, require the session failed timeout value of configuration server end, suitably turn this value down; But still need requesting interval greater than " heartbeat " script; Consider network delay, can on " heartbeat " interval basis, add 5 minutes in addition, and optimize with the fine setting of practical business running environment.
The invention has the beneficial effects as follows:
(1) alleviates the memory cost of server end, promote response performance and concurrent capacity that WEB uses.
(2) avoid frequent and overtimely land again, guarantee that user's excellent operation experiences.

5, embodiment
The part of several keys below the method for maintenance active sessions has mainly comprised in a kind of BS framework portal application:
(1) HTML asynchronous " heartbeat " processing scripts: " heartbeat " asynchronous request timer is installed, is triggered to the WEB application server with timer and send " heartbeat " request, handle " response " result.
(2) the WEB application module of WEB server-side processes " heartbeat " response: accept " heartbeat " request, return success response, application server can help to upgrade session status simultaneously.
Asynchronous " heartbeat " Request Processing sequence is following, as shown in Figure 2:
1) timer in the browser page triggers, and sends " heartbeat " request to the WEB application server.
2) WEB uses and receives " heartbeat " request, upgrades the state of response session, returns success and confirms response.
3) browser receives that " heartbeat " confirm response, waits for that next timer triggers, and changes step 1 and continues, if overtime or receive the response failure, then continues to attempt, attempt certain number of times (, configurable) as 3 times after, if still failure, the prompting user conversation lost efficacy.
" heartbeat " asynchronous call timer installation procedure is following, as shown in Figure 3 in the browser page:
1) browser loads the html page that returns from server.
2) page initialization script begins to carry out.
3) create the script timer that regularly calls " heartbeat " request.
4) accomplish other initialization operations.
5) page initialization is accomplished.
Claims (3)
1. method that in BS framework portal application, keeps active sessions; It is characterized in that: the DHTML script in the browser page regularly (utilizing DHTML script timer) sends asynchronous HTTP request to the WEB application server, loses efficacy because of overtime to avoid current login sessions.Utilize the course of work of door of the method following:
1) user passes through browser to the WEB server requests page.
2) the WEB server returns the page of browse request.
3) the browser initialization page, the DHTML script in the page are called " heartbeat " request here periodically to the specific URL of the asynchronous request of WEB server.
4) WEB server update session status, and respond the request of step 3 with simple success (HTTP return state sign indicating number 200).
2. a kind of method that in BS framework portal application, keeps active sessions according to claim 1 is characterized in that: the time cycle of step 3 said " heartbeat " request is lower than the session timeout settings of WEB server.
3. a kind of method that in BS framework portal application, keeps active sessions according to claim 1; It is characterized in that: step 3 said " heartbeat " request; The protocol header control WEB server and the institute that utilize http protocol to provide forbid this request of buffer memory through gateway, agent equipment, perhaps use HTTP query argument (HTTP QueryString) at random to avoid request to be buffered simultaneously or separately.
