The difference between post request and get request in Ajax

First, different functions

1. Get obtains data from the server.

2. Post transmits data to the server.

Second, the process is different

1. Get adds the parameter data queue to the URL referred to in the ACTION attribute of the submission form, and the value corresponds to each field in the form, which can be seen in URL.

2. Post is through the HTTP post mechanism, each field in the form and its contents are placed in the HTML HEADER and transferred to the URL address referred to by the ACTION attribute. The process is not visible to the user.

Third, get different values

1. For get mode, the server uses Request.QueryString to get the value of the variable.

2. For post mode, the server uses Request.Form to obtain the submitted data.

Fourth, the amount of data transmitted is different

1. The amount of data transmitted by get is small and cannot be larger than 2KB.

2. Post transmits a large amount of data, which is generally unlimited by default. But in theory, the maximum amount of IIS4 is 80KB and 100KB in IIS5.

Fifth, the security is different

1. Get security is very low.

2. Post has high security.

If there is no encryption, their security level is the same, any listener can listen to all the data.
