Big and mean ones.) You can use *inline C* to extend Varnish. Please note that you can seriously mess up Varnish this way. The C code runs within the Varnish Cache process so if your code generates a segfault the cache will crash. One of the first uses of inline C was logging to `syslog`.:: # The include statements must be outside the subroutines. C{ #include <syslog.h> }C sub vcl_something { C{ syslog(LOG_INFO, "Something happened at VCL line XX."); }C } To use inline C you need to enable it with the ``vcc_allow_inline_c`` parameter.
