IME, most websites respond to the Accept-Encoding header, or at least send uncompressed data in the absence of it. I normally do not send this header and I almost always receive uncompressed data. Sometimes there are rare exceptions. (For these I excpetions usually test with Accept-Encoding: identity.) I am generally curious about these exceptions, hence the comment. At least once, the website operator responded indicating it was due to a configuration error.
