I was using zlib function from PHP in my Rebol/Flash dialect but the Rebol compress function IS gzip compression...

gzip-test there are just 4 bytes on the end that means length of the string (I think that may be ignored):
>> print to-string zlib/decompress head remove/part tail compress "gzip-test" -4
gzip-test Rebol'sdecompress is working as well:
>> decompress zlib/compress "gzip-test"
== "gzip-test" I really don't know why RT didn't said that sooner... when I was asking them in the feedback some time ago why there is no gzip compression when Rebol can save PNG files, there was no reply from them:-( never mind... now I can be independent on the PHP... good work Jose
