The awesome tool Web Development Helper allows me to see ALL the http requests from the browser (IE6/IE7) to the server. However the tool does not seem to work in IE8-RC1.
Does IE8 developer tools have a similar feature built in?
If yes, how do I access it?
TIA

My preference is Fiddler, it works with all browsers I know of.

I just created new ASP.NET MVC 4 app, and while inspecting network traffic, I noticed numerous of GET requests.
This is a screenshot of traffic:
http://pokit.org/get/?59050db88c766d3310943b4bbe391de2.jpg
These are request headers http://pokit.org/get/?80e8e84398dfc838938438ec33e5dd92.jpg
So, request occurs every 6 seconds. Could this happen because I installed DevExpress (doesn't make any sense).
Please help, thanks
I guess, this is just an activity related to the browserLink, see http://vswebessentials.com/features/browserlink. This is Visual Studio feature, to sync your css, inspect code and so.
There can be some requests, when in debug mode, because browserLink is doing it's job.
This is very annoying at sometimes.
So there is a documentation about this feature.
And how to disable it - just uncheck it.
Is there any way to access webkit JavaScript and HTTP errors that happen when capturing a page with CutyCapt? I'm trying to debug a thumbnail capture for JavaScript generated documents.
This is not currently possible. I would recommend using a tool like Wireshark to debug any HTTP errors that might occur. It would be easy to add tracing code for network replies to CutyCapt and there are some patches on SourceForge and/or GitHub that do that. I am not sure what could be done to trace JavaScript errors, but ordinarily there should not be any that do not also occur when a page is loaded in a browser. Qt comes with a sample application that implements a rudimentary web browser that could be used for this purpose. I think it also comes with the standard debugger, but I might be misremembering that.
In Matlab Function Alphabetical Reference I only found the following function:
web - Open Web site or file in Web or Help browser
Isn't there a way of accessing a web resource without opening a browser?
Or how to close the browser?
I tried web stackoverflow.com -browser and it doesn't open the browser, but fiddler tells me that no web resource was fetched because of this command.
Edit Somehow Fiddler doesn't gets the Matlab http traffic, so I guess that the web url -browser command works for me, but I'd rather use the urlread command as suggested
urlread might do the job. In case of proxy issues this post might help as well.
Looking at the implementation you might see that The MathWorks is heavily relying on Java libraries.
Have to say I really don't understand how come this could happen:
I've done some code in html, css and a little bit of javascript, nothing fancy,
and just uploaded to two host servers, one to my commercial hosting, the other to uni server.
The funny thing is my commercial server renders exactly as what I can see on localhost, which is of course the expected result. However, the page rendering on uni server is a nightmare:
The CSS stylesheets, although are retrieved from server (verified using Firefox and checked http responses), do nothing to page elements as if there were not there...which I don't understand why?
There is nothing different in my code I believe, I've used two different FTP tools to transfer the code. The only different that I can tell are the server environments, particularly one is Apache 2.0+ and the uni Apache 1.3.3
But I reckon client-side code would not really depend on Apache server versions, would it?
Thanks for any suggestion in advance!
The server where it doesn't work is sending the CSS file back with the wrong MIME-type (text/plain instead of text/css). Recent browsers are liable to ignore CSS files that don't carry the correct MIME-type. So yes, it is an issue of server configuration (mod_mime for Apache).
There is a class library project with embedded javascript file, with a lot of functions (clint-side implementation), is it possible to debug them?
If I set breakpoints inside this file, they never break.
You can, but there is some setup involved - there's an explanation here:
http://weblogs.asp.net/scottgu/archive/2007/07/19/vs-2008-javascript-debugging.aspx
Once set up it works pretty much the same way you'd debug server-side code.
Edit: I should add that it depends what you're doing as to where is the best place to do your debugging. If you're strictly doing client side debugging then I'd suggest using Firebug etc as suggested by the other answers, if you're moving between client and server side code then it's less clumsy to use the Visual Studio tools as above.
You need to debug javascript client side with something like Firefox/Firebug, FirebugLite, or IE8 Developer tools.
Debugging JavaScript has to be done via the client. Breakpoints in the back end would never be triggered because the back end never actually runs the code.
The method for debugging JavaScript varies by browser. For Internet Explorer, there is an Internet Developer toolbar and a Script Editor that will help. For Firefox, tools such as the FireBug addon are very helpful.
