Is there a way to find out the destination of the information or track where it goes when form instance information is created from document.submit?
I have to reverse engineer this application that is taking form submissions but I am having difficulty trying to find out where it's going.
If you are using a modern web browser, like Chrome, you can use the network developer tools within to help you.
You can access the Chrome developer tools with the F12 key and also Ctrl+Shift+i and then go to the network tab. network tools example here. There you will be able to click on individual requests and see the request headers and response data, along with any other relevant data.

While trying to extract information from a web page, I tend to use the console in the web developer tools to write some simple javascript to get the DOM elements and capture the data I need.
I tend to treat the web developer console as an REPL and I would like to save those code snippets for possible re-use in the future. Spark repl has a very useful command :save which saves all the commands from the session to a file so I can replay it later.
Is there such a feature in firefox web developer console to save the commands in the current console session?
I couldn't find any mention of such thing in the user documents. My google search and stack overflow search also turned empty. Only thing I've come close to is Scratchpad, which can be enabled from the web developer tools settings, but it doesn't seem to fit my need.
I'm looking for a tool that would list all the network information that a html dom (javascript etc as well) page loads. Exeactly what chrome shows on the developer tools/Network tab.
I've tried the Chromium-browser under ubutu to export this data but was not able to get the networking stats.
So what I would need is to parse a request preferably thru the command line (ubuntu/debian) which would return the networking stats.
There is network monitor at Firefox dev tools. Take a look at mdn page where this feature is explained. It is possible to export HAR information from the Network panel by right-clicking and selecting "Save all as HAR". HAR is a network request archive format used by many performance and request analysis tools.
You can also use firebug addon which has also his own network monitor and extract data by using the netexport firebug extension.
For automated process (that will open the browser, then firebug, then the page and then will export data), you probably need the auto-tool used for testing firefox which is called mozmill
When I use some website, is it possible to get the url of ajax requests, current page sends. By the help of browser or another tool.
Chrome Developer Tools or Firebug will do the trick. Fiddler is another good tool.
Look in the Net tab of the browser's developer tools, or use a logging proxy like Charles.
We are trying to figure out how something works on the web (for web scraping/automation) and one of the web pages we are working on issues a popup to do some of the work. One of our most commonly used debug tools is the Chrome network tab in Developer Tools, hit "record" do some work, and then examine what was done and then replicate the work done "offline".
However the Developer Tools (in Chrome, Safari and Firefox - all work the same) do not follow requests across a popup, even if you hit "record".
Is there some configuration value I'm missing, or some way to record all network events? We can't use tcpdump/wireshark for this because it's all done over SSL. One option we've considered is a man-in-the-middle https proxy, but I can't find anything pre-written so we'd have to create one ourselves.
I don't know of any way to follow the requests across pop-ups, as each window has its own Web Inspector, however you can use Fiddler to inspect HTTPS requests. It will MITM, and subsequently throw a certificate error, which should allow you to inspect all requests in the order that they happened.
You can use Charles Web Debugging Proxy, which is an app that lets you see all the traffic and even replace some responses with your own. Of course that may break HTTPS so you have to accept the certificate errors, but that's usually a minor problem. It works on Win, Mac and even Linux.
The object inspector cannot inspect what isn't in the current page. Therefore, you will need to open the inspector inside the popup url with same parameters in order to see what it does.
As a tool, you can use a web sniffer to see exactly which url were called during the process.
Like in fiddler you can watch the logs between client and server. Like fiddler; which logs all HTTP(S) traffic between your computer and the Internet. I want to inspect all traffic happening on the client side JavaScript that runs on a page.

You can do this best using Firebug for Firefox :)
When you open firebug, open the net panel and you can see all traffic the browser's dealing with. If you want just the AJAX requests, there's a bar under the main tabs, select XHR.
There's more info available on the net section of the firebug site.
If I misunderstood the question and you want to see all javascript activity, then Firebug does this as well, just open the Console panel and click profile, this will let you see what's happening on the client with all javascript.
As an aside, if you need an IE specific tool, I'd really recommend dynaTrace AJAX Edition (also free!). It's a very in-depth profiler specifically tailored for IE.
