Sometimes we need to control the expiration time of webpages such as home pages. For example, if we use Chinacache CDN, how should we design it so that it can cache my content. of course, you must first enable the reload_assist_ims on function in CDN. in this way, no-cache is not used. this will convert no-cache to If-Modified-Since. therefore, we can write a program to control If-Modified-Since. note: in the cache system architecture, it is best to c

data is inserted or updated, the PHP Cache is forcibly updated. 5. static cache: The static cache mentioned here refers to static, which directly generates HTML, XML, and other text files. it is re-generated once when there is an update. this is suitable for pages that do not change much. 6. memory cache: Memcached is a high-performance, distributed memory object PHP Cache mechanism system that reduces database loads in Dynamic Applications and improves access speed. 7. php buffer: 　　There are

10. DNS round robin BIND is an open-source DNS server software, which is too big to be mentioned. you can search for it by yourself. I know that chinacache and other major sites are doing this. Simply put, they are multiple servers and cache the same page or file on different servers, it is automatically resolved to the relevant server by north and south. The data cache mentioned here refers to the database query cache. each time you access

; Proxy_connect_timeout 90; Proxy_send_timeout 90; Proxy_read_timeout 90; Proxy_buffer_size 4 k; Proxy_buffers 4 32 k; Proxy_busy_buffers_size 64 k; Proxy_temp_file_write_size 64 k; Example of apache mod_proxy: The code is as follows: ServerName bitsCN.com ServerAdmin admin@zxsv.com # Reverse proxy setting ProxyPass/http://bitsCN.com: 8080/ ProxyPassReverse/http://bitsCN.com: 8080/ # Cache dir root CacheRoot "/var/www/proxy" # Max cache storage Cac

access speed. 7. php buffer: There are eaccelerator, apc, phpa, and xcache. you don't need to talk about this. you can search for a bunch of them and read them by yourself. if you know what it is, OK. 8. MYSQL cache: This is not code-level. the classic database uses this method. See the following running time, such as 0.09xxx. 9. reverse proxy-based Web cache: For example, Nginx, SQUID, mod_proxy (apache2 and above are also divided into mod_proxy and mod_cache) 10.

extension effect is the same even if no Web Service is added. 4. The compression ratio setting does not work for JS files, and the size is always the same after compression. 5. The size of the image file remains unchanged even if Gzip is enabled. VII. Summary This article summarizes how to enable gzip compression in IIS. in my project half a year ago, I enabled gzip for my website. Today, I want to organize my own knowledge so that I can review it when I forget it. in addition, Gzip compre

0x00000095 (hexadecimal) or 149 (decimal ). If it is too troublesome, set it to 0 and enable automatic running and playback on all device types. If no NoDriveTypeAutoRun key value exists, create a new NoDriveTypeAutoRun key value.8. uninstall conflicting software. Remember which software is installed before the automatic playback dialog box is displayed, such as Nero, PowerISO, MagicISO, Alcohol 120%, Motorola driver software, VMWare Server, VMWare Workstation may cause this problem.

You can see an option to run the program as a different user. For example, you can temporarily use higher permissions when using a restricted account of your child at home.In fact, this is not a new feature. It can also be done in Windows XP, but in Vista, Microsoft does not "get" it. Very good. Microsoft has changed its min
