257
+
258
+ CloudFlare has developed a plugin for WordPress. By using the CloudFlare WordPress Plugin, you receive:
259
+ <ol>
260
+ <li>Correct IP Address information for comments posted to your site</li>
261
+ <li>Better protection as spammers from your WordPress blog get reported to CloudFlare</li>
262
+ <li>If cURL is installed, you can enter your CloudFlare API details so you can toggle <a href="https://support.cloudflare.com/hc/en-us/articles/200168246-What-does-CloudFlare-Development-mode-mean-" target="_blank">Development mode</a> on/off using the form below</li>
263
+ </ol>
264
+
265
+ <h4>VERSION COMPATIBILITY:</h4>
266
+
267
+ The plugin is compatible with WordPress version 2.8.6 and later. The plugin will not install unless you have a compatible platform.
268
+
269
+ <h4>THINGS YOU NEED TO KNOW:</h4>
270
+
271
+ <ol>
272
+ <li>The main purpose of this plugin is to ensure you have no change to your originating IPs when using CloudFlare. Since CloudFlare acts a reverse proxy, connecting IPs now come from CloudFlare's range. This plugin will ensure you can continue to see the originating IP. Once you install the plugin, the IP benefit will be activated.</li>
273
+
274
+ <li>Every time you click the 'spam' button on your blog, this threat information is sent to CloudFlare to ensure you are constantly getting the best site protection.</li>
275
+
276
+ <li>We recommend that any user on CloudFlare with WordPress use this plugin. </li>
277
+
278
+ <li>NOTE: This plugin is complementary to Akismet and W3 Total Cache. We recommend that you continue to use those services.</li>
279
+
280
+ </ol>
281
+
282
+ <h4>MORE INFORMATION ON CLOUDFLARE:</h4>
283
+
284
+ CloudFlare is a service that makes websites load faster and protects sites from online spammers and hackers. Any website with a root domain (ie www.mydomain.com) can use CloudFlare. On average, it takes less than 5 minutes to sign up. You can learn more here: <a href="http://www.cloudflare.com/" target="_blank">CloudFlare.com</a>.

+ The CloudFlare WordPress Plugin ensures your WordPress blog is running optimally on the CloudFlare platform.
10
+
11
+ == Description ==
12
+
13
+ CloudFlare has developed a plugin for WordPress. By using the CloudFlare WordPress Plugin, you receive:
14
+
15
+ * Correct IP Address information for comments posted to your site
16
+
17
+ * Better protection as spammers from your WordPress blog get reported to CloudFlare
18
+
19
+ THINGS YOU NEED TO KNOW:
20
+
21
+ * The main purpose of this plugin is to ensure you have no change to your originating IPs when using CloudFlare. Since CloudFlare acts a reverse proxy, connecting IPs now come from CloudFlare's range. This plugin will ensure you can continue to see the originating IP.
22
+
23
+ * Every time you click the 'spam' button on your blog, this threat information is sent to CloudFlare to ensure you are constantly getting the best site protection.
24
+
25
+ * We recommend any WordPress and CloudFlare user use this plugin. For more best practices around using WordPress and CloudFlare, see: https://support.cloudflare.com/hc/en-us/articles/201717894-Using-CloudFlare-and-WordPress-Five-Easy-First-Steps
26
+
27
+ MORE INFORMATION ON CLOUDFLARE:
28
+
29
+ CloudFlare is a service that makes websites load faster and protects sites from online spammers and hackers. Any website with a root domain (ie www.mydomain.com) can use CloudFlare. On average, it takes less than 5 minutes to sign up. You can learn more here: [CloudFlare.com](https://www.cloudflare.com/overview.html).
30
+
31
+ == Installation ==
32
+
33
+ Upload the CloudFlare plugin to your blog, Activate it, and you're done!
34
+
35
+ You will also want to sign up your blog with CloudFlare.com
36
+
