Now, online shopping is popular all over the world, open shop on the internet has become the most fashionable and hottest topic. followed by various styles of online mall system launched, and each system has its unique, may give users in the selection system when the "Xuan read", Smart users in the selection of online mall system should be from the system security, stability, ease of use and evaluation factors such as comprehensive consideration, this direction is very correct. However, when considering various factors, we tend to overlook a point, and it is very important that the whole station generates HTML static. Why so say, I personally experienced in the recent online shopping products, merchandise pages can not open events, to know the Web page can not open the business is a kind of how heavy blow.
Events, 2012 Suning easy to buy 818 promotional activities, I would like to buy a gree during the activities of the air conditioner, but because the product page can not open the next step, dozens of refresh the page, the page has been in a blank state, and finally did not successfully buy this product. What caused this, my computer is 4M broadband, the usual internet, watching video, online shopping basically will not have any problems, why in Suning promotional activities can not successfully buy their own goods, I think is not a computer or broadband problems, the reason should be in Suning system, Suning low-cost sales activities, Inevitably caused by consumers crazy snapped up, resulting in a large system traffic, system server overwhelmed paralyzed, so that the page can not open the situation.
Afterwards, I also found in the relevant news of the industry to Suning easy to buy blockbuster promotional activities, but encounter the page is not open, the cause of the network paralysis analysis, it is because of the site in the face of a sharp increase in access, traffic surge, because of the harsh system requirements, the system performance of the great challenge, and the page can not open the situation. If you do not increase the server immediately, reduce the pressure of the system, even the possibility of system paralysis. At the same time, some industry experts speculate that if the system foreground output page is to generate HTML static, the implementation of the page static, it can effectively alleviate, or even meet the large number of visits, traffic huge increase in the page will not open or paralysis, because the site generated HTML static can enhance the load capacity of the site, reduce the server , the database pressure, and does not need to add the server method to reverse the system pressure, and increases the service to be cramming, is cannot fundamentally solve the system pressure problem. Similar events, in the November 11, 2011 Jingdong Mall Book promotional activities appeared, when the east side is to take the increase of twice times the server to alleviate, but the situation is not imagined optimism, until the end of the activity, Jingdong system to return to normal.
Why is the generation of HTML static to the system when a large number of visitors have affinity, Dynamic Web page can not do? We analyze, similar to suning easy to buy, shopping malls of the order of magnitude should be more than hundreds of thousands of, day clicks should not be less than millions of times, we know, Any online product or Web page content is to upload to the website server can be published, if the page is generated HTML static, then the Web page content in the service is a separate file. Dynamic Web pages are not independent of the service, only when the customer clicks on the request server to return to a complete page. Just imagine, in suning easy to purchase activities, a commodity page in a minute by normal 20 clicks, suddenly increased to 2000 times or more clicks, the system can be carried down? If the product page is a dynamic technology, in a minute, All of a sudden, 2000 users click the request server to return to the full Web page, then the service response can be timely? In fact, in the early days there have been many users to do similar stress tests, dynamic Web pages in a sudden encounter in the big visit, it is impossible to get timely response, very easy to appear on the Web page can not open, and even the situation of system paralysis. If the site is generated HTML static, in the sudden encounter a big visit, the situation is more optimistic, because the HTML static Web page on the server is a stand-alone file, no matter how many times click, just to open the existence of the file, and this is any server can do.
Above said so much, we summarize the generation of HTML static to the role of the site, hope to help users.
1, the site generated HTML static, can effectively enhance the load capacity of the site, reduce the server, database pressure;
2, the site generated HTML static, you can make search engines more affinity, effectively improve the speed of Web site access, you can speed up the page opening speed, improve the number of search engines and site rankings;
3, the site generated HTML static, you can make your site in a safe mode, static page theoretically what is the loophole attack;
4, the site generated HTML static, you can make errors in the database is still normal access, the site will not be due to the small database problems caused by the whole station paralysis;
5, the site generated HTML static, the use of virtual host users more convenient, because the site in the design of the product size, color and other intelligent selection parameters, commodity classification in (price, shelf time, popular) on the sorting and need pagination, if not generate static page, easy to cause the server pressure too big problem;
6, the site generated HTML static, the hard disk will not cause any damage, because the generation of HTML static Web site than ordinary Dynamic Web hard disk write frequency is 2 times higher, but because the generation of HTML static Web site content will almost no longer be modified, the number of hard disk writes can be negligible, So will not cause any damage to the hard disk;
Of course, there are disadvantages to benefit, the disadvantage of the next opportunity to talk about.
Through the above story, users open shop in the selection of online mall system is not a new perspective, choose a good, appropriate their own system, not only to consider the system security, stability, ease of use and evaluation, but also to consider the system in the face of a large visit, the system's affordability. I recently also compared to a variety of online mall system, generate HTML static such as shop++ in this aspect to promote doing more, interested netizens can go to the official website to understand respectively.
