PHP's hyper-global variable $ _ COOKIE brings a lot of convenience and may also cause confusion in some cases. For example, if a cookie with the same name exists in the root domain and subdomain, $ _ can only save one COOKIE. Which one should it be?We recommend that you use the longest RFC, which has the highest precision, but different browsers have different processing methods. I only tested Chrome. In Chrome, cookies with the same name in the r

A Web site with several or n pages, they are identified with the URL, we do site optimization, nothing more than to make these URLs as far as possible to get a better ranking, did the optimization of the people know that the URL structure on the site optimization is also influential, then the child domain name and subdirectory which is more suitable for optimization? Now let's look at the pros and cons of the domain name and subdirectory: The difference between a child domain name and a subdire

Once it is found that it has changed, hash is used to obtain the required information.The implementation of this method is complex and has limited functions. In IE and FireFox, the URL length can be about 2000 characters. It may be enough for a common requirement. Unfortunately, it is far from enough to transmit a large amount of data. Compared with the solution we will propose later, its only advantage may be that it can make asynchronous requ

device.Therefore, an IRP may be forwarded multiple times. In order to record the operation of an IRP in each layer of equipment, the IRP will have an array of io_stack_location (stacks, positions). The number of elements in the array should be greater than the number of devices traversed by the IRP. Each io_stack_location element records the actions that are made in the corresponding device. For the corresponding io_stack_location of this layer device, it can be obtained by iogetcurrentirpstack
