java - Session logout/ timeout -

-

to make short, here scenario:

  • the browser button must functional (i'm using jsf 2.0, working)

  • after logout, if user clicks button, app must redirect him/her login page (not working, user able view protected pages, although expired. can´t include meta tags disable browser caching because button stops working)

  • if user invokes action, clicking button, on 1 of expired pages should redirect him/her login or error page (not working, app throws error , shows blank page. exceptionhandlerwrapper implementation detects exception , using navigationhandler change viewid , render response ("facesexception" mapping on faces-config points login.jsf), app not behaving expected)

can please me solve problem?

  • after logout, if user clicks button, app must redirect him/her login page (not working, user able view protected pages, although expired. can´t include meta tags disable browser caching because button stops working)

two steps solve problem.

  1. disable browser cache setting response headers accordingly. can in filter mapped on facesservlet.

    httpservletresponse hsr = (httpservletresponse) response; hsr.setheader("cache-control", "no-cache, no-store, must-revalidate"); // http 1.1. hsr.setheader("pragma", "no-cache"); // http 1.0. hsr.setdateheader("expires", 0); // proxies. chain.dofilter(request, response);

  2. do not use http post page-to-page navigation. use http page-to-page navigation. if need submit form, let submit self (i.e. let action method return null or void) , use h:messages or h:somecomponent rendered="#{success}" display results in same page conditionally.

  • if user invokes action, clicking button, on 1 of expired pages should redirect him/her login or error page (not working, app throws error , shows blank page. exceptionhandlerwrapper implementation detects exception , using navigationhandler change viewid , render response ("facesexception" mapping on faces-config points login.jsf), app not behaving expected)

an <error-page> on javax.faces.webapp.viewexpiredexception been enough. see this answer.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
