Sending http PUT / GET / DELETE / POST requests from a browser
May be UrlParams or Tamper Data can help. But
Modifying arbitrary HTTP traffic in Chrome is impossible, because Google hasn't exposed an API to extension developers yet that would make this possible. But I also doubt Google will expose such a low-level API in the future, because all their present APIs are pretty high-level.
as said in question Is there an extension like Tamperdata for Chrome?
I've been using Advanced REST client on chrome.
