hi, what is the difference between serving a file directly or by calling a script function? case 1: http://localhost/myfile.xml case 2: http://localhost/mydir/boo/getfile Must I do special call to apache api when compression is activated? With Firefox, every thing works fine in two cases. With a http client component I'm using in my developpements, both case 1 and case 2 works fine if I don't ask for compressed data. If I do (Accept-Encoding: gzip), case 1 works fine but case 2 fails. I noticed that returning apache.OK adds unexpected extra "0" on the output. thanks.
