HTTP Content-Length and Chunked Transfer-Encoding. Is there a 2GB Limit?

Question

Is a HTTP Content-Length over 2GB or 4GB supported by modern webservers?

How about the chunks in HTTP Chunked

Answer 1

From what I have gathered, 64-bit limits are new, especially in the web browsers. Chrome supports them, Opera maybe, and I see a patch for Firefox that hasn't landed yet. I've read posts that say IE returns negative Content-Length, which means it's likely to use 32-bits.

64-bit HTTP lengths looks like the future, but we aren't there yet.
