This includes when a new post is 17 | added, a post is updated or when a comment is posted to your blog. 18 | 19 | To keep widgets like "Recent posts", "Recent comments" and such up to date, you should consider using ESI 20 | and include them through a text widget for arbitrary text or HTML. 21 | 22 | Installation 23 | ------------ 24 | 25 | This section describes how to install the plugin and get it working. 26 | 27 | 1. Install the plugin 'WordPress Varnish' through the 'Plugins' menu in 28 | WordPress 29 | 2. Activate the plugin through the 'Plugins' menu in WordPress 30 | 31 | Frequently Asked Questions 32 | -------------------------- 33 | 34 | ### Does this just work? 35 | 36 | Yes. 37 | 38 | ### But how should my varnish configuration file look like? 39 | 40 | I have provided a simple VCL that can be used as a reference. 41 | 42 | ### Does it work for Multi-Site (or WPMU)? 43 | 44 | Yes. Activating the plugin site-wide will provide the functionality to all 45 | blogs. Configuration can be done on the blogs individually, or can be global. 46 | If you want to configure Varnish servers globally, edit wp-config.php and 47 | include these lines just before "That's all, stop editing!" message: 48 | 49 | > global $varnish_servers; 50 | > $varnish_servers = array('192.168.0.1:80:secret','192.168.0.2:80:secret'); 51 | > define('VARNISH_SHOWCFG',1); 52 | 53 | The varnish servers array will configure multiple servers for sending the 54 | purges. If VARNISH_SHOWCFG is defined, configuration will be shown to all 55 | users who access the plugin configuration page (but they can't edit it). 56 | 57 | ### My Plugins are seeing the Varnish server's IP rather than the websurfer IP 58 | 59 | You could install Apache's mod_rpaf module: http://stderr.net/apache/rpaf/ 60 | 61 | or, in wp-config.php, near the top, put the following code: 62 | 63 | $temp_ip = explode(',', isset($_SERVER['HTTP_X_FORWARDED_FOR']) 64 | ? $_SERVER['HTTP_X_FORWARDED_FOR'] : 65 | (isset($_SERVER['HTTP_CLIENT_IP']) ? 66 | $_SERVER['HTTP_CLIENT_IP'] : $_SERVER['REMOTE_ADDR'])); 67 | $remote_addr = trim($temp_ip[0]); 68 | $_SERVER['REMOTE_ADDR'] = preg_replace('/[^0-9.:]/', '', $remote_addr ); 69 | 70 | The code takes some of the common headers and replaces the REMOTE_ADDR 71 | variable, allowing plugins that use the surfer's IP address to see the 72 | surfer's IP rather than the server's IP. 73 | 74 | Screenshots 75 | ----------- 76 | 77 | 1. Screenshot of the administration interface. 78 | 79 | Changelog 80 | --------- 81 | 82 | ### 0.8 83 | * Added secret handling to WPVarnishPurgeObject, Thanks Kit Westneat 84 | * Change WPVarnishPurgePurgeCommonObjects to WPVarnishPurgeCommonObjects, 85 | Thanks kitwestneat 86 | * added @ to supress Undefined offset notice 87 | * minor doc changes 88 | 89 | ### 0.7 90 | * Added purge when post changes from future to publish, Thanks Marcin Pietrzak 91 | * Added purge when theme switched, Thanks dupuis 92 | 93 | ### 0.6 94 | * Removed plugins_loaded action as it doesnt do what was expected re: Issue 95 | #12.

This 14 | includes when a new post is added, a post is updated or when a comment is 15 | posted to your blog. 16 | 17 | To keep widgets like "Recent posts", "Recent comments" and such up to date, 18 | you should consider using ESI and include them through a text widget for 19 | arbitrary text or HTML. 20 | 21 | == Installation == 22 | 23 | This section describes how to install the plugin and get it working. 24 | 25 | 1. Install the plugin 'WordPress Varnish' through the 'Plugins' menu in 26 | WordPress 27 | 2. Activate the plugin through the 'Plugins' menu in WordPress 28 | 29 | == Frequently Asked Questions == 30 | 31 | = Does this just work? = 32 | 33 | Yes. 34 | 35 | = But how should my varnish configuration file look like? = 36 | 37 | I have provided a simple VCL that can be used as a reference. 38 | 39 | = Does it work for Multi-Site (or WPMU)? = 40 | 41 | Yes. Activating the plugin site-wide will provide the functionality to all 42 | blogs. Configuration can be done on the blogs individually, or can be global. 43 | If you want to configure Varnish servers globally, edit wp-config.php and 44 | include these lines just before "That's all, stop editing!" message: 45 | 46 | global $varnish_servers; 47 | $varnish_servers = array('192.168.0.1:80:secret','192.168.0.2:80:secret'); 48 | define('VARNISH_SHOWCFG',1); 49 | 50 | The varnish servers array will configure multiple servers for sending the 51 | purges. If VARNISH_SHOWCFG is defined, configuration will be shown to all 52 | users who access the plugin configuration page (but they can't edit it). 53 | 54 | = My Plugins are seeing the Varnish server's IP rather than the websurfer IP = 55 | 56 | You could install Apache's mod_rpaf module: http://stderr.net/apache/rpaf/ 57 | 58 | or, in wp-config.php, near the top, put the following code: 59 | 60 | $temp_ip = explode(',', isset($_SERVER['HTTP_X_FORWARDED_FOR']) 61 | ? $_SERVER['HTTP_X_FORWARDED_FOR'] : 62 | (isset($_SERVER['HTTP_CLIENT_IP']) ? 63 | $_SERVER['HTTP_CLIENT_IP'] : $_SERVER['REMOTE_ADDR'])); 64 | $remote_addr = trim($temp_ip[0]); 65 | $_SERVER['REMOTE_ADDR'] = preg_replace('/[^0-9.:]/', '', $remote_addr ); 66 | 67 | The code takes some of the common headers and replaces the REMOTE_ADDR 68 | variable, allowing plugins that use the surfer's IP address to see the 69 | surfer's IP rather than the server's IP. 70 | 71 | == Screenshots == 72 | 73 | 1.
