javascript - Back button filter not working -

-

I have configured a filter to disable the back button on my browser and when the session ends, is shown. This is working as expected when my application is configured in prototype, but when I have included it in my (Spring MVC) application, it does not work.

I have configured my filter like this 

  & lt; Filter & gt; & Lt; Filter-name & gt; BackButtonFilter & lt; / Filter-name & gt; & Lt; Filter range & gt; Com.filters.BackButtonFilter & lt; / Filter-class & gt; & Lt; / Filter & gt; & Lt; Filter-mapping & gt; & Lt; Filter-name & gt; BackButtonFilter & lt; / Filter-name & gt; & Lt; URL pattern & gt; / * & Lt; / URL pattern & gt; & Lt; / Filter-mapping & gt;

And I had such a filter element 

  response.setHeader ("Cash-control", "No-cache, no-store, Re-verified "); Response.setHeader ("pragma", "no-cache"); Response.setDateHeader ("Ended", 0); Response.setHeader ("cache-type", "private");

I have presented the log statement to see if my filter is being executed or not. I can see it execute.

Why is this happening?

May I suggest using the HTTP header to see the end of the browser?

Edit To see one thing, make sure that the HTTP header is being written before all HTTP Body

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
