HTTP protocolConcept: rules that govern which objects are subject to compliance!!!Http protocolHttp protocol: Hypertext Transfer Protocol (Http:hypertext Transfer Protocol) is one of the most widely used network protocols on the Internet. All WWW documents must comply with this standard .Features of the HTTP protocol:* The HTTP protocol complies with a request-response pattern. (Request, response).* Requests and corresponding must appear in pairs.* Must have an existing request after a response.

occurrence of such conversions. Therefore, as a programmer, we should improve our own quality, rather than simply complete the task. Well, this is beyond our scope. After talking nonsense, we will continue to come back to the topic.
We have already taken the initiative to convert encoding to unified encoding, so we can't help but think about it. Are there other methods? The answer is yes. tomcat has long considered these questions for us, but how much do we know about it? Next we will first mak

HTTP requestsOpen Eclipse, "File", "New", "Dynamic Web Project", enter the project name, Dynamic Web module version Select 2.5, click Done. (about how Tomcat is integrated into Eclipse, as shown below)To open the project, create a new form.html form page under WebContent, as follows:Start WEB12, then use IE browser to access localhost:8080/web12/form.html, use the plugin installed on IE
recommended to use the HttpWatch described below4. HttpWatch Tools:HttpWatch is provided specifically for IE and Mozilla Firefox, to view HTTP requests and the corresponding tools, which are helpful to our developers and enable us to learn the HTTP protocol better.Once the installation is complete, you can see the plugin in Internet Explorer:Clear the browser cache, re-enter the URL, the effect is as follo

This way we not only get the dynamic identity of the Web page, but also set it to the requestparams that will be submitting the form.
So we rebuilt a params1, this time all the form information has been set to it, the following simulation log in:

In general, the header of HTTP contains the Content-length field to indicate the length of the newspaper style.
Sometimes the service generates HTTP response is unable to determine the size of the message, such as large file download, or the background requires complex logic to all the page request, when the need to generate a real-time message length, the server generally use chunked encoding. There are two options for using chunked encoding, one is to set the server's IO buffer length so that
HTTP protocol monitoring plug-in
When doing web development, the HTTP protocol is generally well encapsulated, and does not directly see the HTTP protocol first-class original content, but these things are often very helpful to us to find the problem. There are two Firefox plugins that can be easily implemented.

In the previous section, we implemented the HTTP request Header content parsing and printing to the console, so that each component of the HTTP request header was completely exposed to us. This function in IE browser is called HttpWatch plug-in has a similar embodiment, I believe many readers have used it, using HttpWatch to view the Web page request and response log information function to debug the progra

Recently found a "stingy" learning site. Site content should not let replication, so do, how to let us test the time to make small copy, it is difficult not to a word a word to play. Fortunately, we are engaged in technology, this problem is still difficult to fall, you do not allow replication just right, this I still lazy trouble. It would be more convenient to take a script directly to remove the contents of the lesson.
Say to do, first look at the source code. However, the Web page
Because in the transmission of the server and the client only byte stream to complete the transmission of data, then we can add a flag in different numbers.
The graph is the HTTP message captured by HttpWatch
This source of thought originates from HTTP request and response messages, simulates HTTP requests and responses, I specify the first byte in the stream of bytes {0: text, 1: file, 2: Shake}.
But at this time there is

As for "through the cable in clear text of the way ...", in fact, this sentence is very wrong, first of all, the cable is only a transmission medium, which transmits only electrical pulses, light signals, and so on, rather than network protocol messages (learned computer networks are known). As for the "Use of the form of clear text," is not true, in fact, "Basic Authentication", is the user name and password used BASE64 encoding, int

3 most critical, just draw the correct "contour" (remember HttpWatch and other tools to print out the head?) That's what "silhouette" means, and there will be points, but it would be a shame if the contours were written wrong.
