a magic tool to solve the problem of slow website opening
what should i do if the website is opened slowly? what should i do if the website bandwidth is low? the website will get stuck as many visitors! most people may say that it’s enough to buy a better server!
but what if you don’t have that much budget? today's suyou network (www.szfangwei.cn)teach you a website to speed up magic- CDN accelerate.
it can not only greatly increase the website opening speed, but also increase the website bandwidth without limit. more importantly, it has a very cost-effectiveness.
the following examples of alibaba cloud CDN traffic fee, 100 GB only 20 yuan, it is very cheap, and can be used for virtual hosts, which can greatly increase the capabilities of virtual hosts and use virtual hosts. +CDN acceleration, as long as the configuration is properly configured, the effect can be compared with independent hosts with a price of more than 10,000 yuan.
the steps for activation are as follows, alibaba cloud is currently available here CDN as an example:
step 1: open CDN accelerate service;
step 2: enter CDN accelerate management and add domain names, as shown in the figure below, generally select small image files for business types. in the case of http select port 80 for regular websites. HTTPS select port 443 for the website.
step 3: resolve the corresponding domain name CNAME value to specified generated CDN domain name, as shown in the figure below (i won’t introduce it here for details on how to parse the domain name)
step 4: the analysis is completed and it can be basically used, but i realized that CDN the hit rate is very low, what's going on? here, suyou network prompts you because there is no cache set. click configure to enter the following cache page settings
step 5: modify the configuration and set the cache rules. the following figure is just a reference:
multiple rules can be set according to the directory and file suffix name, generally, static image files are set first. CSS document, JSS file caching rules. this type of file is generally rarely modified after the website is online, so you can set the cache time for a long time. if you modify it later, you can add file parameters.
the second is to set the directory that needs to be cached. the weight in the figure above is that when several rules conflict, the one with the higher weight shall prevail.
if you do not need to cache dynamic files, such as the website search function page, set the cache time to 0.
how to set it up, each website may be different, and you can set it up according to your own needs.
CDN acceleration can cache files of your website to various regional servers according to the cache set, thereby reading them recently, greatly speeding up website access. so how do you think CDN is the acceleration cache effective?
open the website and use Chrome the kernel browser, press F12 open the website front-end debugging function and switch to the network TAB you can view the menu, as shown below
this is the official website of suyou.com http://www.szfangwei.cn of F12 online screenshots, mainly look at the pictures X-Cache yes HIT still MISS， in the case of HIT it means that the cache file is read and the MISS it is to read the source file.
there is another parameter below X-Swift-CacheATime indicates the cache time X-Swift-SaveTime indicates the time when the file was started to be cached.
CDN in addition to speeding up website opening, there are many functions, such as anti-theft link, intelligent compression, HTTPS、IP blacklist, page optimization, etc.
the speed of the website opening not only affects the speed of the visitors opening, but also affects the search engine's rating of your website. therefore, you must pay attention to it. if you are not clear, you can consult the customer service of this website.
