+Deflate/Inflate:
+ http_inflate() resp. the HttpInflateStream should be able to inflate
+any compressed data (gzip, deflate AKA zlib and raw deflate). However,
+inflating raw deflated data causes a re-initialization of the inflate
+stream where the corresponding window bits are modified to tell libz
+to not check for zlib header bytes. This is not preventable AFAICS.
+ http_deflate() resp. the HttpDeflateStream should be able to
+generate any compressed data (gzip, deflate AKA zlib and raw deflate);
+just use the flag for the data format you want to generate:
+ HTTP_DEFLATE_TYPE_GZIP, HTTP_DEFLATE_TYPE_ZLIB or HTTP_DEFLATE_TYPE_RAW.
