使用 .htaccess 优化网站

Question

我尝试使用 YSlow 获取指导来优化我的网站。但是，即使我在 .htaccess 中添加了 DEFLATE 代码来对文件进行 gzip 压缩，YSlow 仍然不会将文件显示为 gzip 压缩的。我尝试使用以下方法测试我的网站： http://www.gidnetwork.com/tools/ gzip-test.php 它显示我的网页未 gzip 或压缩。我还能如何将它们压缩或压缩？

这是 .htaccess：

SetOutputFilter DEFLATE
Header unset ETag
FileETag None

################ Expires Control ################
ExpiresActive On
ExpiresDefault A0
<FilesMatch "\.(gif|jpg|jpeg|png|swf)$">
# 2 weeks
ExpiresDefault A1209600
Header append Cache-Control "public"
</FilesMatch>
<FilesMatch "\.(xml|txt|html)$">
# 2 hours
ExpiresDefault A7200
Header append Cache-Control "proxy-revalidate"
</FilesMatch>
<FilesMatch "\.(js|css)$">
# 3 days
ExpiresDefault A259200
Header append Cache-Control "proxy-revalidate"
</FilesMatch>

除此之外，我还能做些什么来优化网页的速度并减少加载时间？

此外，每次刷新页面时，页面上的图像都会不断加载。如何缓存它以使其快速加载？

Answer 1

您可以尝试启用“mod_gzip”

将其放入您的.htaccess

<ifModule mod_gzip.c>
  mod_gzip_on Yes
  mod_gzip_dechunk Yes
  mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
  mod_gzip_item_include mime ^text/.*
  mod_gzip_item_include mime ^application/x-javascript.*
  mod_gzip_item_exclude mime ^image/.*
  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>
