[英]Redirect loop with Cloudflare on Drupal website
I have problems recently after enabling Cloudflare on my Drupal website. 在我的Drupal网站上启用Cloudflare之后,我最近遇到了问题。
After few minutes working on my website, I get redirect loop Cloudflare 521 error page, telling me that web server is down, after a couple of seconds I get my site working. 在我的网站上工作了几分钟后,出现重定向循环Cloudflare 521错误页面,告诉我Web服务器已关闭,几秒钟后,我的网站开始工作。 This happens really often, I need help. 这种情况确实经常发生,我需要帮助。
I have searched a lot about this, and I have done already several things: 我对此进行了很多搜索,并且已经做了几件事:
-I set SSL settings to Full(Strict) on cloudflare settings, -我在cloudflare设置中将SSL设置设置为“完全(严格)”,
-Added page rules on cloudflare, -添加了关于cloudflare的页面规则,
-SSL is enabled already on the server, -已经在服务器上启用SSL,
Also, I added these lines in .htaccess file: 另外,我在.htaccess文件中添加了以下几行:
# Redirect to HTTPS
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
to redirect everything automatically to https. 将所有内容自动重定向到https。
This problem appears whether I am on https or http version of my website. 无论我使用的是https还是网站的http版本,都会出现此问题。
I'm quite a beginner with this. 我是一个初学者。
EDIT I have also cleared Drupal, Cloudflare and browser's cache (Chrome, Firefox, Opera are tested), updated database also just in case. 编辑我还清除了Drupal,Cloudflare和浏览器的缓存(已测试Chrome,Firefox,Opera),以防万一,还更新了数据库。 Still nothing. 依然没有。
use below code. 使用以下代码。
RewriteRule ^ - [E=protossl]
RewriteCond %{HTTPS} on
RewriteRule ^ - [E=protossl:s]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^ index.php [L]
