When i request a page, I need to get the returned data and changed it before viewing it
How can i do that in Awesomium?
It depends if you are using Awesomium with C++ or C#.
Awesomium for C++ provides a ResourceInterceptor class to intercept requests and responses:
ResourceInterceptor API for C++
Unfortunately, Awesomium for C# doesn't provide the same thing. There is only an interface to catch Requests, but no equivalent for catching Responses.
IResourceInterceptor API for C#
Different possibilities from here:
Tweak Awesomium for C# to implement this
Use a 3d party tool like Fiddler to intercept and modify requests/responses
In the latter case, you can find useful resources here:

I have been looking for a way to make API calls to the Docusign REST API using strictly client-side javascript (no Node). I haven't been able to find a single example of how to do this which leads me to believe it's not possible for some reason.
Furthermore I haven't seen an SDK for client side javascript calls. Only the following are available: C#, Java, Objective C, Node, PHP
https://www.docusign.com/developer-center/api-overview#sdk-docusign
So my question is this, is it possible to make purely client side calls to the Docusign API?
Not fully from a client side, due to CORS restrictions for security purposes.
I'm using WebKitGTK+ ( WebKit ) application that will be a very simple web browser running in a Linux environment as a separate executable that will need to exchange data between another application. The system is described in the following image:
Example scenario:
Event such as smart card insertion detected in Backend processing Application
smart card data is read and passed to the WebKitGTK+ GUI Application
User interacts with "web page" displayed in WebKitGTK+ Application
Data is passed from WebKitGTK+ Application back to the Backend processing Application
What are the common methods of passing data between the WebKitGTK+ Application and the Backend processing Application?
Does `WebKitGTK+ provide some hooks to do this sort of thing? Any help at all would be appreciated.
I know this is a old question, but will try to answer it to best of my abilities so that it can be useful to someone else.
Webkit is basically rendering a html page. You can connect to various signals that webkit provides and act on these signals. More details at http://webkitgtk.org/reference/webkitgtk/stable/webkitgtk-webkitwebview.html
For your back end application, if something interesting happens, you can update page either by navigating to a new url, new page contents or just by setting text of desired element. Webkit provides DOM api functions and all of these are possible.
It becomes interesting when getting data from webkit and sending it to your back end system. Again, this depends upon your specific design, but generally you can hook up signals such as navigation signals when user clicks on a button and get contents. Another alternative is to use alert handler and simply use javascript alert and process the alert data on backend side.
Shameless plug for example : https://github.com/nhrdl/notesMD. It uses a simple database backend, probably can be good use case as it sends data back and forth between database and webpage. Even manipulates the links so that desired actions take place.
I am looking for a way to control a web browser such as firefox or chrome. I need something like "selenium webdriver" but that will allow me to open many instances URL load, get http headers, response code, get response content, load time, etc.
Is there any library, framework, api that I could use to do it? I couldn't find one exactly that does all, selenium opens browser and go to url but I can't get http headers
Selenium and Jellyfish are strong options in general. Jellyfish is an option that uses Node.js - although I have no experience with it, I've heard good things from my colleagues.
If you just want to get headers and such, you could use the cURL library or wget. I've used cURL with NuSOAP to query XML web services in PHP, for example. The downside is that these are not functional browsers, and merely perform the HTTP requests and consume the response.

I want to know how and which things are used to make google docs and box.net ?
Most of the UI functionality comes from using Javascript and HTML's DOM together with AJAX, a technique for using JS to make additional requests of the server without reloading the page.
In terms of the back-end languages (that provide the dynamic content) box.net returns PHPSESSID as part of it's set-cookie http response. They're also running nginx. So I would suspect one of the many PHP frameworks as being in use.
As for google docs, Google are known to use python quite extensively. Google's "App Engine" uses Python or Java as its languages (I believe Python was added first). So I suspect they use some customised form of python based on their own instance of their own app engine. Their http headers give nothing away, except that the Server: GSE line.
According to HowStuffWorks, Google Docs uses Java for the backend and JavaScript for the front end. Of course, HTML is in the mix there as well.
As for the database it uses, Google won't say. It will use the cloud though, we can be sure of that.
I need to implement a browser plugin which can register its own protocol (like someprotocol://someurl) and be able to handle calls to this protocol (like user clicking on 'someprotocol' link calls function inside my plugin). As far as I understand, Skype does something similar, except I need to handle links within page context and not in a separate app. Any advice on how this can be done? Can this be done without installing my own plugin, with the help of flash/java?
Things are going to be slightly more complicated than you think.
You're going to have to create an entire application, not just a browser plugin (that plugin can be part of your application). The reason I consider it to be a complete application is that you're going to need to modify registry settings on the client machine to register your custom URL handler.
Here's an MSDN article describing exactly what you have to do to register the custom URL handler on a Windows client:
