1 Now to do is click on the first to enter the evaluation page all future parameters are related to this address.Xkkh=(2013-2014-2) -05b31067-0311-1

Select all to save and go to the next comment

2 continue to evaluate, notice which parameters have changed

This is the first time the argument is submitted

Here you can see more data on the post form here, which is the first time the data is saved.

There are many parameters passed from the first page, the server took the last time we recorded the operation, the encryption section is, and then as one of the parameters of this submission, resubmit

3. Save the above and open the next review page

Look at the post data of the first review page

As with the previous basic, only that the encrypted section of the __viewstate is different, prove it is very important, every time you save the submission is used

The following is still the same analysis,.... (All the Submit button clicks before that are not responding)

4. It's the last page.

Because I first filled out after the click on the save, so the following parameter changes, but we can be completed after the completion of a direct click Submit, and the first save completed in the submission effect is the same, just indicate that the entrance is not the same.

Click Submit to see

That Button1 turned into a Button2 , and of course, the encryption in front of it.

Supposedly the most important thing is that this step is submitted by the various parameters, so it is necessary to look at the encryption of what the content, the general use should be Base64 encryption bar

If so, see the decrypted content. So we're not going to be able to forge a paragraph like this one, and then encrypt the post to solve it?

It seems to see or not understand the ... Or be honest every time you get over and save it at the submit insurance point.

The following simulation data are submitted 1. Open the simulation on the First review page

Post past and then remove __viewstates as parameter

Because each account corresponds to a different number, that is, some parameters are different, to the last commit is good.

This information can be obtained according to the analysis;

Suppose we have 6 subjects, named A,b,c,d,e,f, corresponding to a teacher's number 1,2,3,4,5,6
Working process on a webpage:
1. Click on an Account evaluation link to enter the evaluation page
2. Tick-Check for positive feedback
3. Save (less than the last one cannot be submitted)
4. Click the Save button to transfer to the next account review, until the last one, at which time you can submit
5. Completion of the submission, all evaluations completed.
