I use node.js to develop app, I want simulate some bad internet situation when people surfer on the internet,
like limit the data transfer speed, or delay some css or js file transfer
How can I achieve these goals?Is there some goal can do this?
I have used fiddler in the past to test unstable/slow internet connections on my apps. Fiddler has a modem speed option. Set that and you get incredibly slow speeds. You can also download a plugin called Delayed Responses, it will delay the packets from arriving back at to your app.
If that isnt up your ally, then I would suggest looking for a web based proxy that will allow you to control the parameters of the requests you want. Just google it.
