| Output Compression

| so enable only if you are reasonably sure your visitors can handle it.

| Only used if zlib.output_compression is turned off in your php.ini.

| Please do not use it together with httpd-level output compression.
|
||||
|
|
||||
| VERY IMPORTANT: If you are getting a blank page when compression is enabled it
|
||||
| means you are prematurely outputting something to your browser. It could
|
||||
| even be a line of whitespace at the end of one of your scripts. For
|
||||
| compression to work, nothing can be sent before the output buffer is called
