open source cache server

Do you know which of the most expensive cloud servers we use? Run the memcached cache server (12G RAM). Do you know who is one of the contributors to the speed of Web Access? Run the memcached cache server. With the cloud server so noble memory run memcached is too extravag

The previous article has introduced the Memorycache,memorycache storage data type is object, also said Redis support v data type of storage, but Microsoft's Redis cache component only implemented hash type of storage. Before you analyze the source code, learn a few commands about Redis operations.One, Redis command All Redis commands are described in detail on the http://doc.redisfans.com/. Here are a few c

table instead of caching the file content. Use the CacheFile command in the configuration file to specify this method of cache. This command tells httpd to open the file at startup and reuse the file handle for subsequent accesses to the file. For example, CacheFile/usr/local/apache2/htdocs/index.html. Although CacheFile does not cache the file itself, it also m

display. Because this kind of dynamic page technology usually needs to obtain the data from the data source, and passes some computational logic, finally becomes some HTML code to send to the client to display. And these computational processes are clearly costing. These processing costs are most directly manifested as impacting the responsiveness of the server, especially when data processing becomes comp

prohibits the browser and all intermediate caches from storing any version of the return response, such as a response that contains personal privacy data or bank business data. Each time a user requests the asset, it sends a request to the server and downloads the full response."Public" and "private"If the response is marked as "public", the response can be cached even if it has associated HTTP authentication, and even the response status code is usu
