In general, we can direct the user to download files by directly having the URL point to a file located under document root.
However, in doing so, there is no way to do some statistics, permission checks, etc. work. So, a lot of times, we use to make PHP to do forwarding, to provide users with file downloads.
$file = "/tmp/dummy.tar.gz";

The biggest difference between the two UA strings and the ordinary UA string is that there is a "SV1" sign in it. What does this mean? SV1 is intended to be "Security Version 1", which is used to indicate whether the operating system used by users using the IE 6 browser is XP SP2 or WS03S
I made a business to judge the browser type and version number, and recorded the relevant js code. I personally feel pretty good, you can refer to the following two days to make a business that judges the browser type and version number, and record the relevant js Code:
The Code is as follows:
Function allinfo (){Var ua = navigator. userAgent;Ua = ua. toLowerC
In front-end development, you often need to determine the browser version to ensure compatibility with multiple browsers at the same time. Below are two good common methods: Comments in jquery and HTML, if you like it, you can refer to the following methods to search for browsers and versions on the Internet. Here, the younger brother sums up two methods to save your time.
1. jquery method:
Regular Expressions can be used to determine common browsers and their versions.

In the SIP application, if a user is using the sip ua to enjoy a certain time-based service, such as watching a pay-as-you-go TV online and suddenly crashes, the server will not be able to know any information about the user's device crashes, the billing service continues.
This is obviously an unreasonable situation. The server must know the user's status in real time. In this case, the Presence Server may not be able to solve the
One rowCodeThis solution solves various Internet Explorer compatibility issues. In website development, Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, and Internet Explorer 10 may not suffer from compatibility issues, in fact, Internet Explorer provides a solution. Google also provides a solution. Baidu also applies this solution to solve ie compatibility problems.Source codeAs follows One line of code solves various ie compatibility issues, including IE6, I
In addition to its own method, it is certainly not to use navigator. useragent to determine the browser. In the early days of the first browser war, Netscape was an absolute statistical position. Most people were reluctant to be compatible with other browsers and checked its UA to allow their websites to only access Netscape, this forces other browsers (including IE) to modify their UA to pretend to be Nets

Section 8th, 10, 11, 12, 13, 14, and 15 describes the complete UA core (section 9th describes cancellation and is used in UA core and proxy core ). Section 16th describes proxy servers, which are used for message routing between two UA instances.

6. How to synchronize remote and local files?
My $ code = mirror ('HTTP: // www.yahoo.com.cn ','/path/file.html ');
The mirror function compares the consistency between the remote and local files, and returns a status number. For example, if the file is the same, 304 is returned. If the local file is synchronized successfully, 200 is returned.
7. How to test whether the returned status is correct?
