Varnish Software announced that they finished implementing SSL in Varnish Cache Plus.
The release will happen at at Varnish summit in Silicon Valley in early June.
Varnish Cache Plus is both a HTTP server and a HTTP client and both implementations will have SSL enabled. The HTTP Server, ie the client facing SSL is perhaps the most significant one, enabling Varnish Cache Plus to encrypt traffic between the client and Varnish.
Varnish Cache offers several ways to log and most of the documentation is related to varnishlog which includes several information related to request, response and backend response. Now what’s happen if we need to log our own variables or message to a file?
The key function is std.syslog enabled via std (standard) Varnish module, which is the only built-in “vmod” and is thus natively available and doesn’t have to be compiled.
then you can easily add into your VCL the following line:
std.syslog(180, "log description");
The first parameter, 180, is the priority value. If you want to add some variables to your log message:
std.syslog(180, "log description" + beresp.ttl);
This will logo the message to general system log, which is often, in a Linux system, is located in /var/log/messages.
