ASP uses XMLHTTP to implement code for form submission and sending cookies

Indeed, if form submission or cookie verification exists on the original website, it is difficult for ASP to do so without using socket-based components. In fact, the other two methods of XMLHTTP are ignored, this is the key to the problem.

The method is described as follows:

1 .. Send ()
Because popular thieves use get instead of post to transmit data, many people ignore this method, and sending data using send is also very simple, that is, send ("content"). However,

Sending a form is not that simple, because if the form you send is in Chinese, it will involve encoding.

First, you need to determine whether to use Post (that is, post). Open ("Post", address, or asynchronous) during open ).

Then, add the content of your form to send. For example, the form you want to submit has three form fields: A, B, and C. The corresponding values are 1, 2, 3. In this case, you can submit the form in send ,. send ("A = 1 & B = 2 & C = 3"). How is it easy? Didn't you think of it? But don't be too happy. As I mentioned earlier, if the form value is Chinese, data transmission will fail. Here we use an escape () function, so anyone familiar with JavaScript should know the function's role. Now VBScript also supports this function .. Send ("A = escape ('value 1') & B = escape ('value 2') & C = escape ('value 3 ')").

2 .. SetRequestHeader ()
As mentioned above, when your data is sent, the other party will not receive it. Why? In fact, it is because your HTTP header has missing something, then you can use this function to add it, specifically. setRequestHeader ("Content-Type", "application/X-WWW-form-urlencoded") tells the other party that you have submitted a urlencode-encoded form.

Okay, let's talk about how to send cookies after the form is submitted.

In fact, sending cookies is also very easy. I also use this function to add things to the HTTP header. For example, my current outdated cookies are
Cdb_sid = ybbik0; cdb_cookietime = 315360000; cdb_oldtopics = d869008d; cdb_visitedfid = 1d45; cdb_auth = signature % 2fbaijb1lucg; cdb_fid45 = 1113370145
Now I want to send this cookie directly. setRequestHeader ("cookie", "cdb_sid = ybbik0; cdb_cookietime = 315360000; cdb_oldtopics = d869008d; cdb_visitedfid = 1d45; cdb_auth = signature % signature; cdb_fid45 = 1113370145 ")
Of course, some website pages have the page judgment function, which is not difficult, that is,. setRequestHeader ("Referer", "lailu absolute address ")
