different regions. But as you can see, the pages in these countries are a little bit abnormally low. Cucumbertown is an asset-heavy web site, and although we postponed all the action on Requiejs and then actively loaded JavaScript on demand, we made a lot of effort to load the underlying script. We have confirmed that Cucumbertown's loading time in the United States is 2.5 seconds, compared to other countries this is simply the speed of light, DSL equipment around the world a week delay is 43

servers or arrays to the Internet are considered "upstream", those farthest considered "downstream"). This allows the cached content to be as close to the user as it needs it. Arrays are highly scalable because you can add servers to the array or increase the array level to a hierarchical architecture without disrupting the current caching solution. Another scalability issue is the ability to use caching to reduce network bandwidth for branch offices. The branch office agent may not be connec

tutorial channel Some large web companies have their own CDN, but the cost of using CDN services like Akamai Technologies, Mirror image Internet, or limelight Networks is very high. For start-ups and personal sites, it may not be possible to use CDN's cost budget, but as the target user base expands and becomes more globalized, CDN is required to achieve fast response. In the case of Yahoo, the static content of the website program they transferred

allows you to specify an HTTP GET or http POST parameter to change the cache entry. For example, just set the varybyparam= "a" to default.aspx? Report=1 or default.aspx? report=2 for output caching. You can also specify additional parameters by specifying a semicolon-delimited list.Many people don't know when to use output caching, and the ASP.net page also generates some HTTP headers downstream of the cache server, such as the headers used by Microsoft Internet Security and Acceleration Server

Friends in the process of using the computer, inevitably encounter a lot of sudden failures, the cause of these failures may be caused by software, but also may be caused by hardware failures, or other factors, then we are the primary computer users how to deal with these events, please see below: suffered a power outage phenomenon: monitor, host, speaker, etc. will be "forcibly closed" in a flash. Phenomenon Analysis: This is a sudden "blackout

reuse it multiple times. The maximum time is 60 seconds. Then, the page will be re-executed, the output will be added to ASP again.. NET cache. You can do this by using some low-level programmable APIs. There are several configurable settings for the output cache, such as the VaryByParams attribute just mentioned. VaryByParams is requested, but you can also specify http get or http post parameters to change the cache items. For example, you only need to set VaryByParam = "Report" to set the def

that 80-90% 's end-user response time was spent on various elements of the download page, such as files, stylesheets, scripts, and Flash. Instead of the difficult task of refactoring the system, it is better to distribute the static content first. This not only greatly reduces the response time, but also due to the existence of CDN, the distribution of static content is very easy to implement.A CDN is a collection of geographically distributed Web servers that you use to publish content more ef

Mozilla, Cisco, Akamai, Identrust, eff, and University of Michigan researchers announced the Let's Encrypt CA project, which plans to provide free SSL certificates to the Web site, accelerating the transition of the Web from HTTP to https. Let's Encrypt CA project plans to automatically release and manage free certificates from the summer of 2015 to any Web site that requires encryption certificates.The biggest obstacle to deploying HTTPS is the compl

As a result, these files will be backed up in many CDN data centers around the world.Static content often represents the bandwidth size of the site and can be easily replicated through a CDN. A third-party CDN is usually used by the website. For example, Facebook's static files are hosted by Akamai, the largest CDN provider.For example, you might get a response from a akamai.net server when you try to ping static.ak.fbcdn.net.

semicolons.When using the output cache mechanism, many people do not know that ASP. NET pages also generate a set of downstream Cache Server HTTP headers, such as the HTTP headers used by Microsoft Internet Security and Acceleration Server or Akamai. When an HTTP cache header is set, the document can be cached to these network resources, so that you do not have to return the original server to respond to client requests.However, using the page output

network and market their services. However, the CDN service provided by Alibaba Cloud is relatively simple and lacks complex CDN technical support and weak experience. In particular, the network coverage of a single operator is limited, and the obstacles to cross-network services are hard to provide independent CDN services for enterprises. This is a barrier that cannot be broken through when operators develop their CDN services. It is understood that China Telecom began to invest in CDN servic

Some large websites have their own CDN, but it is cost-effective to use services provided by CDN service providers such as Akamai Technologies, Mirror Image Internet, or limelight networks. In yahoo!

distribution Network". Facebook uses content distribution networks (CDNs) to distribute static files like images, CSS tables, and JavaScript files. As a result, these files will be backed up in many CDN data centers around the world.Static content often represents the bandwidth size of the site and can be easily replicated through a CDN. A third-party CDN is usually used by the website. For example, Facebook's static files are hosted by Akamai, the l

Internet Security and Acceleration Server or Akamai. After the HTTP cache header is set, documents can be cached on these network resources, and client requests can be satisfied without returning the original server. Therefore, using the page output cache will not make your application more efficient, but it may reduce the load on the server, because the downstream cache technology will cache documents. Of course, this may only be anonymous content;

can be directly read from the cache. The server response contains the retention period of static files, so the browser knows how long it will take to cache them. In addition, each response may contain the ETag header (the object Value of the requested variable) that works like the version number. If the browser observes that the file version ETag already exists, stop the transfer of this file immediately. Try to guess"Fbcdn.net"What does the address represent? The smart answer is "Facebook cont
