重定向页面速度问题

标签: .htaccess redirect web opencart pagespeed

我试图在所有运行良好的网站上强制使用WWW但是当我进行页面速度测试时,我得到以下建议(例如):

Remove the following redirect chain if possible:

http://swing-and-play.com/catalog/view/theme/shopzone/image/social/facebook500.png
http://www.swing-and-play.com/catalog/view/theme/shopzone/image/social/facebook500.png

这是我的htaccess:

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled. 

# 2. In your opencart directory rename htaccess.txt to .htaccess.

# For any support issues please visit: http://www.opencart.com

Options +FollowSymlinks

# Prevent Directoy listing 
Options -Indexes

# Prevent Direct Access to files
<FilesMatch "\.(tpl|ini|log)">
 Order deny,allow
 Deny from all
</FilesMatch>

# SEO URL Settings
RewriteEngine On
# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/

### Additional Settings that may need to be enabled for some servers 
### Uncomment the commands by removing the # sign in front of it.
### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.

# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it:
# php_flag register_globals off

# 2. If your cart has magic quotes enabled, This may work to disable it:
# php_flag magic_quotes_gpc Off

# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try
# php_value upload_max_filesize 999M

# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value post_max_size 999M

# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_execution_time 200

# 6. set max time for input to be recieved. Uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_input_time 200

# 7. disable open_basedir limitations
# php_admin_value open_basedir none

你能帮我找到这里的错误吗?

答案 0 :(得分:2)

该错误表示您在没有www。的情况下链接到图像,因此正在重定向请求。

在HTML中找到指向http://swing-and-play.com/catalog/view/theme/shopzone/image/social/facebook500.png的引用并修复它。
