How to trap browser close event in SERVER side?
I read a lot of forum message, it talk about onclose(), onunload() and even
onbeforeunload( ) event. However, all of theses are based on javascript
written on the client browser , like IE. To send a POST to web server to
acknowledge its close event.
However, I just think, web server and client browser is a TCP connection.
And if the client browser is close and it imply the TCP socket is broken.
The web should detect the connection lost, Right? Is there any method that
the web server(server side) can detect this?
I'm cope for ASP.NET solution with IE browser as majority.
Thanks for any help

HTTP is stateless. There is no persistent connection between browser and
server. Therefore, no, there is no method to do what you want.

You can use the IsClientConnect ed property of the Response object.
It can be useful to check for user still connected for "heavy" tasks to
complete.

Could you not use Javascript to catch the browser window close event to
launch another page that would inform the server? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi,
When user closes a browser window by clicking on the "X"
button, I want the server to be noticed (either through
postback or calling other ASP pages, etc.) and perform
some task accordingly. Please note that I can't use
session end event, since the session is still alive now
and the user is just closing a secondary window he/she
opened.

I want to detect, if user has close the browser, (after logging to my site),
that user has closed the browser. How to achieve it ? I want to know this
close action on my server-side code. Because if he logout by clicking on
Logout/ Sign-Off button it simple to get the message.
Although, this is very similar to the first above. Also, if user takes any
action on client-side or browser side how will I detect...

Hi everyone,
I need some help (may be in the form of some sample code) for the subject
question.
I have an ASP.NET/C# application. I need to do quite a few tasks when the
session ends. I don't want to depend on the session timeout factor since it
may end too soon or it may hang around too long. I can't find any event
that fires when the browser closes. The Session_End event handler in the
Global.asax does not execute until the...

I need to capture the event when the user closes the browser in my
application. I have some code in the session_End event, which works fine
when the session times out, but I need to end the session immediately when
the user closes the browser.
Does anyone know a way of doing this?

Hello
I am new to asp but I made some Jscript functions which work
fine. The functions contain some strings used as a registration
key for some apps. It is important that these strings not be
visible to a client using a browser. My question is...can a
knowledgeable browser user view Jscript source code in an asp file?

Another fellow here must modify an application. On the web page, pressing

If the enter key is pressed, do the submit method. If F6 is pressed,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
