-If you keep getting "SSL connect error" when trying to issue requests on
-Windows, try another (newer) libeay32.dll/ssleay32.dll pair.

-Inflating compressed HttpRequest responses happens twice if libcurl
-was built with zlib support.
+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.
+ Using an encoding stream filter on a stream you read from, will
+not work as expected in a PHP version lower than 5.1.3.
