I'm trying to find the most efficient way to send my Linq2Sql objects to my jQuery plugins via JSON, preferably without additional code for each class. The EntitySets are the main issue as they cause not only recursion, but when recursion is ignored (using JSON.NET's ReferenceLoopHandling feature) a silly amount of data can be retrieved...

Hello there, I am currently putting together a rails-based web application which will only serve and receive data via json and xml. However, some requirements contain the ability to upload binary data (images). Now to my understanding JSON is not entirely meant for that... but how do you in general tackle the problem of receiving bina...
It seems to me that any interception of this could provide instant trouble because anyone could just send any HTML/script back to the client. The only reason I'm interested in doing this is because of the huge pain it is for front-end developers every time there's a DOM structure/CSS change so you now have to go figure out where in the ...
I have been thinking quite a bit here lately about screen scraping and what a task it can be. So I pose the following question.

I've been doing a project at work recently focused on an almost entirely client-driven web site.

Hi, I am writing a JSON response from a perl/cgi program. The header's content type needs to be "application/json". But it doesn't seems to be recognized as response is thrown as a text file.

MGraph is a great textual data format brought by Microsoft "Oslo". Do you think it has a chance to get as broad as XML is today? Example (Google Geocode): { name = "waltrop, lehmstr 1d", Status { code = 200, request: "geocode" }, Placemark [ { id = "p1", address = "Lehmstraße, 45731 Wa...
This is nuts. I have an ASP.NET MVC application using Windows authentication that, amongst other things, interacts with a number of ExtJs Javascript components by returning JSON data to them. The problem is that even after the user is successfully authenticated, every 5th request to grab some JSON data from MVC results in TWO "401 Unau...
