- If set to on (default), any HTTP response towards clients will
- have the TOS value of the response comming from the remote
- server masked with the value of zph_preserve_miss_tos_mask.
- For this to work correctly, you will need to patch your linux
- kernel with the TOS preserving ZPH patch.
- The kernel patch can be downloaded from http://zph.bratcheda.org
