Petr, I meant to elaborate on some of the simple header checks possible, in the last message:
The gzip header has some very simple things in the header, including a "magic" number (a sort of quick file format identifier). If the first 2 bytes aren't (decimal) 31 and 139, then the file is DEFINITELY NOT gzip encoded. And the next byte is the identifier for the Compression Method. The only one used is 8 for DEFLATE. (I believe. It's been a long time...) So even without any further fancy understanding of the file format, you can VERY QUICKLY rule out the majority of files/responses that are not gzip encoded, if their first 3 bytes don't match these values. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
