Understanding that my problem could have a very vast scope of possibilities, I'll accept the answer that points me to something that I might have missed.
My software's client is facing this issue of page stopping loading in the middle and that too happens randomly. As usual, this does not happen in out network even with guys doing VPN from remotest parts of the world. The page is only 14 KB.
Its a web-based software that serves HTML via Apache over HTTPS. Client is using IE8 browsers.
We did network trace and found that not only number of bytes differ from our end to the trace at client's end, even encrypted packet sequence also differ (after a while in the stream). But that happens for successful request too!
Has someone experienced similar issue? What could corrupt the stream?
PS: I'm not too optimistic on getting answer here and going to post it to serverfault anyway. If someone thinks its off-topic, please feel free to close it.
It may be the operation aborted scenario which throws an error in IE7, but stops processing silently in IE8.
The HTML file is being parsed, and encounters a script block. The script block contains inline script which creates a new element and attempts to add it to the BODY (document.body.appendChild(newElem)) element before the closing BODY tag has been encountered by the parser. Note that if I removed the highlighted DIV element, then this problem would not occur because the script block’s immediate parent would be BODY, and the script block’s immediate parent is immune to this problem.
Unfortunately the operation aborted dialog was always thrown at the top-level of a web page, even if the problem occured in an iframe. In fact, in most scenarios that we encountered, ad injection in an iframe was usually the root cause of this error. After the user dismissed the error dialog, Internet Explorer would navigate away from the page.

In odoo while I am doing any long process such as getting data from
amazon and process those data in odoo and after 5-10 min I am getting
this error don't know the reason why this happen.
XmlHttpRequestError BAD REQUEST
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
Invalid JSON data: ''
The process seems running in background in server but I am getting this error every time. This leads users into the wrong direction.
I am wondering why I am always getting this error? Is that a normal behavior ?
Even data processing will be done properly even after getting this
error, so I am not getting the meaning why this error pop out only in
long process.
Is there timeout issue happen with web server ?
Where I need to look out for that ?
UPDATE
I have did this process from different system and it seems everything
working fine over there.
So what my guess is "It is something related to browser end only"
May be browser is not able to manage such idle requests (may be any
request time out settings needs to be updated)
Solution:
It wasn’t clear at first but the tracing telling me exactly what the problem is “cookie”.
The problem was due to a cookie that has become corrupted. Not sure
how it got that way but it seems that the last time it was generated
something went wrong. The easy solution is to delete all your
cookies of that particular domain or should do this from private
window (incognito mode).
I'm using Zombie.js for testing with Cucumber-js, and I can't seem to get my client side scripts to run.
Visiting the page:
this.browser.visit("http://localhost/boic",function(e, browser,status,errors){
console.log('status',status);
console.log('error',errors);
console.log('console',browser.text("H1"));
});
Returns a status of 200, no errors, and displays the H1 text correctly. However, if I include a script to change the H1 code in the page:
<script>
$('H1').html('hello world');
</script>
The H1 text remains unchanged, and no global variables are accessible via browser.window...
thanks!
Did you load jQuery in your page before the script is called?
there is also the runScripts browser option but that defaults to true.
But I'm gonna recommend running an external phantom.js process and going through the webdriver interface. Just because I spent 6 months trying to get zombie to do what I wanted and phantomjs made it all easy. http://phantomjs.org/release-1.8.html https://github.com/LearnBoost/soda
I agree w/ Jon Biz. Zombie is difficult to work with. Many sites that use JS libraries that might contain minor errors cause it to crash (I think node fails) when the zombie browser encounters them - if you have the runScripts option set. This makes it very hard to use for any application/site that requires external JS - ie most of them.
I also recommend switching to Phantomjs.
I have a project set up using ASP.NET WebAPI on top of Azure, and am having a problem whenever I try to make an HTTP Post where the content-length is too long in the header.
Normally I would've just ignored this problem, because you should be correctly setting the content-length on POST, but it turns out that when this happens, it causes the session to hang indefinitely, and then the Azure emulator crashes.
I have a custom JSON Formatter which extends MediaTypeFormatter, and I set a breakpoint on the first line of my implementation of OnReadFromStreamAsync(). However, the breakpoint is never hit because the hangup happens before ever hitting the JSON Deserializer.
I really have no idea where this hanging is occurring from because I receive no exception, just an indefinite hang and occasional Azure emulator crash.
Thank you in advance for any help or insight you might provide!
This sounds like a bug. The good thing is that you can get updated developer bits form codeplex.
There is a chance what your experiencing is related to one of these:
WebAPI: Stream uploading under webhost is not working
DevDiv 388456 -- WebHost should not use Transfer-Encoding chunked when
content length is known.
Zero ContentLength without content type header in body is throwing
If the updated bits don't fix your problem I suggest you try the standard media formatters to rule in/out your formatter. Failing that, then submit an issue.
I'm working on a site and to help catch errors that we may not hear about, I've created a custom 500 error page.
This page basically records information about the current situation and logs it including the following:
Request.Servervariables("URL")
But, the log seem to actually be providing information about the location of the error.asp file instead of the actual file causing the error. And it doesn't seem to pick up Server.GetLastError().
Any ideas on how to ensure these scripts pick up the errors and deatils about the page causing the error and not the page that is used for 500 errors?
NOTE: When there's an error, the url in the address bar is always the address fo the page causing the error, but the log shows the error handler page 'error.asp'.
I would follow what Dee said, but also be aware that there was something finicky with IIS7 (or 7.5). I can't remember exactly, but you have to do something special to make sure it works on IIS7. Check out this article. IIS7 breaks the server.getlasterror and there is a workaround provided.
Also a cool thing to do is to email yourself those errors. So in your custom 500 asp script just fire off an email with the details. Depends on how critical errors are to your program, but it's good to be in the loop rather than have another log to worry about.
When selenium tries to open popup window I'm getting JS error permission denied in file
file:///C:/DOCUME~1//LOCALS~1/Temp/customProfileDir8708f7f69e14482ba857f4b2e74775c1/core/RemoteRunner.hta
So this break script execution, could you assist? I saw a related topic at MSDN and openqa but didn't find resolution that could help me.
I've just encountered this error. In the end it was because I was running IE in 'Offline' mode. Open the File menu and make sure that "Work Offline" does not have a tick next to it.
I've just updated a section about that in the Selenium docs. The website build is not working right now, so if you go to the site you will find the old version.
I'll paste the raw text here, I think your case is the second: JS trying to access sections that are still not loaded, so your solution would be a waitForPopUp command:
Why am I getting a permission denied
error?
The most common reason for this error
is that your session is attempting to
violate the same-origin policy by
crossing domain boundaries (e.g.,
accesses a page from http://domain1
and then accesses a page from
http://domain2) or switching protocols
(moving from http://domainX to
https://domainX). For this to be
solved, try using the Heightened
Privileges Browsers if you're working
with the Proxy Injection browsers.
This is covered in some detail in the
tutorial. Make sure you read the
sections about The Same Origin Policy
and Proxy Injection carefully.
If the previous situation was not your
case, it can also occur when
JavaScript attempts to look at
objects which are not yet available
(before the page has completely
loaded), or tries to look at objects
which are no longer available (after
the page has started to be unloaded).
This is most typically encountered
with AJAX pages which are working with
sections of a page or subframes that
load and/or reload independently of
the larger page. For this type of
problem, it is common that the error
is intermittent. Often it is
impossible to reproduce the problem
with a debugger because the trouble
stems from race conditions which are
not reproducible when the debugger's
overhead is added to the system. Try
first adding a static pause to make
sure this is the situation and then
moving on to the waitFor kind of
commands.
