使用mod_cache模块

1. 在httpd.conf文件中添加以下代码：

LoadModule cache_module modules/mod_cache.so

2. 配置反向代理服务器：

ProxyRequests Off ProxyPreserveHost On Order allow,deny Allow from all

ProxyPass /api http://api.example.com ProxyPassReverse /api http://api.example.com

3. 在VirtualHost中启用缓存：

CacheEnable disk / CacheRoot /var/cache/localhost/ CacheDefaultExpire 3600 CacheMaxFileSize 1000000 CacheIgnoreCacheControl On CacheIgnoreNoLastMod On CacheEnable disk CacheHeader on CacheDefaultExpire 120 CacheMaxFileSize 1000000 CacheLastModifiedFactor 0.5 CacheIgnoreCacheControl On CacheIgnoreNoLastMod On
