I have written a CSS server which does minimization and basic parsing/var replacement. The server is using node.js.

I am wanting to gzip my response from this server. As told in IRC, node.js does not currently have a gzip lib, so I am attempting to do it manually from the command line (as I am only gzipping when not in cache).

I am pushing the file data out to a temp file and then using exec to call 'gzip -c -9 -q ' + tempFile. I get the compressed data back correctly (it seems), and send the proper Content-Encoding header as 'gzip', but Chrome reports:

Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error.

Also, some independent gzip testers online fail as well (not just Chrome).

I’m assuming this is something simple I do not know about generating gzip blocks for browsers, seeing as I have never tried to do it manually.

Any assistance would be helpful. The server is blazing fast, but I need to gzip the content to get the best performance for end users.

Thanks.

UPDATE
I have verified my Content-Length is correct

    Have you updated the Content-Length to match the gzipped size? It seems like that might screw up the decoding.
