Ah ok, I didn't think you were suggesting mIRC should handle the gzip encoding.
Abstracting http doesn't necessarily mean the response is 'decoded' for you, it could be served as is and we would still call it abstracting, but yeah, handling gzip encoding for us would be awesome.
You're right for the Accept-Encoding header, but I remembered using some broken http servers where using 1.0 was a workaround, but I guess that's irrelevant to the abstraction and it should use 1.1.
