Does Apache httpd server dynamically generate just-in-time (JIT) compiled code?

[Yue Chen]

Hi,

In some OS's, the network stack would compile packet filters to the native
code, like the Berkeley Packet Filter (BPF).

Would Apache httpd server also do this? In httpd, what's the usage of
function ``ap_core_input_filter'', and does this function generate JIT
code?  If it does, will the generated code contain code pointers to its
original static code in ``ap_core_input_filter''?

I go through the source code, but cannot get much sense on what it does and
how it works.

Best thanks and regards,
Yue
