Ajax and IE crash

I have run into a situation that if a page/tab that uses the Ajax toolkit
(using .net version 3.5) is closed before the Ajax enable controls complete
loading, then IE locks up. Does it in both IE7 and IE8. There is no issue
when the controls are allowed to complete loading.

Can you please tell me the best practice that handles this?

Thanks.

Hi,

Do you mean if AJAX toolkit is used, sometimes when you close the browser
the browser will hang? Could you send me a demo project that can reproduce
this problem? My email is v-******@microsof t.com.

Thanks. It only happens when the window/tab is closed before the Ajax driven
controls finish loading. Would take some time to make a project that
duplicates it, separate from my current one (and I am afraid I have to keep
that password protected due to sensitive data).

I am loading 11 drop down lists using the toolkit's Cascading Drop Down. If
these have not finished loading and the tab is closed, then IE hangs up.

Any ideas?

Hi
I tested this page:

http://www.asp.net/ajax/ajaxcontrolt...opDown/Cascadi
ngDropDown.aspx
It seems fine. Can you repro this behavior with that page?

I look forward to your demo project and will test on it.

Here is a link to a project that duplicates the issue:
http://www.criminonwus.org/IECrashTest.zip

If you click on the link on the default page, it opens a new window/tab. If
you close that window/tab before the drop down lists populate and then click
on the link on the default page again, it hangs up (sometimes you have to do
this a couple of time). If you try to refresh the default page, it also
hangs up.

Seems like it shouldn't do this. Any ideas of how to get around this?

Thanks.

Hi

Thank you for your project. I've reproduced this issue on my side. It looks
more like an IE issue than an AJAX Toolkit issue. I'm now investigating it
and will get back to you if I find the culprit.

Thanks. I'm glad you were able to duplicate it, gives me hope it will be
fixed.

Note, this is also an issue with Ajax without using the toolbox. Maybe an
issue with ScriptManager?

The only work around I have come up with is to trap the
window.onbefore unload in javascript and at least give the user the option of
keeping the page open, with a warning that strange things may occur if he
doesn't. This involves a lot of extra coding though, so it would be good if
it got fixed at the source.

Thank you for your project. I've reproduced this issue on my side. It looks
more like an IE issue than an AJAX Toolkit issue. I'm now investigating it
and will get back to you if I find the culprit.

Hi,

I've used Network Monitor to track the http traffic. It looks like IE will
not send new requests to the same domain when the hang happens. What I can
guess so far is, IE somehow doesn't know the connection should be closed if
a user manually interrupts the AJAX request by closing the tab. By default,
as you may know, IE only allows two subsequent connections to one domain.

I've contacted our development team for a confirmation about this issue.
They may need some time to come to a final conclusion. I'll follow up and
update here.

As to your workaround, it's really good. Try to use it temporarily and
let's wait for the conclusion.

Allen Chen

Thanks for your help. Hopefully, this will get fixed so the extra coding
will not be needed in the future.

| | Here is a link to a project that duplicates the issue:
| | http://www.criminonwus.org/IECrashTest.zip
| |
| | If you click on the link on the default page, it opens a new
window/tab.

then

also

| |
| | Seems like it shouldn't do this. Any ideas of how to get around this?

Hi,

From the information given by the development team, this is indeed an
unexpected behavior. We're now investigating this issue.

Besides your workaround we can also edit the registry key to increase the
connection quota:
http://support.microsoft.com/default.aspx/kb/282402

It's another option, but not an ideal solution.

| | Thanks. I'm glad you were able to duplicate it, gives me hope it
will be

| |
| | Note, this is also an issue with Ajax without using the toolbox.
Maybe

Hello, I am writing a no-plugin networked Sketchpad program (DHTML, Comet/Ajax). Because I am trying to avoid using Flash or Java Applet, I rendered my strokes at first with the wz_jsgraphics library (http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm). It turned out that that was too inefficient, and if you drew too many things on the screen firefox would crash. So I looked into SVG for Firefox. This works great because it is...

I see a lot of posts claiming that you can use AJAX or Javascript to run some kind of "heartbeat" " server polling" that tells the server that the page is still open. I need to know how exactly to do this (server side and client side) or where I can find information on doing this. I want to run some code after a page is closed and I don't want to wait for the session timeout. if anyone has information please post explanations, code...

So, I have a summary page of some stuff that gets updated through AJAX calls back to the server every 15 seconds or so. However, if you leave that page up for a few hours - it'll slow down the computer and eventually crash it with the following message: "Internet Explorer: out of memory on line..." I know AJAX got some memory leaks problems but this is not that much stuff that gets refershed ( a few table rows ).

I am having trouble escaping the & in a JSON.stringfy() ajax call. I don't even know if I am stating the problem correctly here. In my app I have linked json2.js from http://www.JSON.org/json2.js 2010-08-25(see attached file) to my app. Then I have created an ajax call in the app to my server_side app in which I invoke the JSON.stringify(dataObj). My "dataObj" is an Associative Array. If one of the array element values contains the "&"...

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. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...

But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
