Twitter sends a POST request of only 13 bytes when someone follows an account. This small amount of information helps to reduce latency and server load, providing advantages for web developers.
However, removing unnecessary cookies and extra information from XMLHttpRequests is not possible due to security reasons. Despite this limitation, can we achieve similar efficiency as Twitter or is it beyond our reach?
The value "13B" represents the size of the response body, rather than the request.
In my opinion, the appearance of "13B" in Chrome's inspector is simply a temporary glitch related to rendering. Once the full response is received, the correct value will be displayed (indicating the size of the response, not the request), as several others have pointed out.
It's worth mentioning that this anomaly does not occur when using Firebug in Firefox or tools like Charles proxy sniffer.
