During recent work, you sometimes need to capture the source address and target URL. It feels good to use several tools.
The first one is wsockexpert made in China. In the past, most people used Internet vulnerabilities. Easy to access, common functions. However, its own DLL files are easily considered to be deleted by Trojans. Suitable for analysis submitted by specific programs.
The second is httpwatch. A packet capture program embedded in IE. The
requested content during this time (this behavior is invalid for F5 or Ctrl + F2, IE7 is used, firefox 3.5 has been tried. valid example: Enter the address and press Enter ).
Expires expiration time
In servlet, you can use response. addDateHeader ("Expires", date. getTime (); to add expired content.
Ps: In httpwatch, the Result is in the (Cached) state.
4. Use the max-age Cache-Control header
The value of max-age indicates the number of seconds af
I am a newbie in the http protocol and packet capturing tool. I only used HTTPWATCH, but I found that AJAX data cannot be captured. Very depressing. Is there a more powerful monitoring tool recommendation? I 'd better pay it to me, or send my QQ mailbox 13676987. thank you, man. you can't do it with fidder ., What kind of AJAX package do you want to capture. If it is only a tool for capturing content http protocol and data packets

The performance loss of this mechanism is that the server's asp.net still receive requests and process requests. The mechanism in this article is to let the browser decide whether to read the cache itself, so that the request for the server is completely eliminated.
1: Reduce static page requests
To allow static pages to support this requirement, we need to use the Cache-control:max-age in the HTTP header. It is noteworthy that the Cache-control is identified under the http/1.1 protocol, which

The product prototype design is diverse, and some common tools can be simply implemented. Of course, there are also some professional tools that can help design faster and faster.
Adobe Flash Catalyst is a new Flash Platform product provided by Adobe. If Flash applications are not developed, it is very easy to use it for Interactive Prototype Development.
Balsamiq Mockup is a prototype tool similar to hand-painted graffiti.
Axure RP is a powerful prototype tool.

We have used the HTTP call process obtained by HttpWatch and obtained detailed information about the HTTP request header and other requests. Since WebServie communicates over HTTP, can we not use HTTPWatch to obtain its request process? Our code is not only the HTTP protocol sent to the server, but also the SOAP protocol, which is the basis for WebService communication.

GoC # Crawl data from websites that need to log onbackground: Yesterday a student of finance, let me help her to crawl data from a Web site, and then exported to Excel, a cursory look at the following 1000+ records, manual statistics words is really impossible. Although not, but as a computer science, I still have the cheek to agree. . The first thought is to send a GET request directly, and then parse the returned HTML will not be able to get the required information? Sure, if it's a site that

Of course, if the last operation was just a GET request rather than a post, repeating commits does not cause this problem.How to prevent duplicate submissionsThe method of preventing duplicate submissions is somewhat similar to the PRG (Post-redirect-get) pattern, specifically, when the Web server recognizes a duplicate-committed POST request, redirects to the current page, and the browser reque

In this blog, I mainly talk about the HTTP protocol, because we developed references based on web pages (B/S ).ProgramDevelopment, so we have to deal with the HTTP protocol. This blog is a preliminary study of how to deal with the HTTP protocol.
