* mod_status - display server status
|
|
*
|
|
* Description:
|
|
* mod_status can display a page with statistics like requests, traffic and active connections
|
|
* it can be customized with different stylesheets (css)
|
|
*
|
|
* Setups:
|
|
* none
|
|
* Options:
|
|
* status.css <name|url> - set the stylesheet to use
|
|
* type: string; values: "default", "blue" or a url to an external css file
|
|
* Actions:
|
|
* status.page - returns the status page to the client
|
|
*
|
|
* Example config:
|
|
* req.path == "/status" {
|
|
* status.css = "http://mydomain/status.css";
|
|
* status.page;
|
|
* }
|
|
*
|
