HTTP400

In the case of HTTP status 400, it is generally caused by a browser cookie .

We encountered an excessive number of cookies in the project, and then there was a bug in browser 400.

The solution for this scenario is as follows:

1. Completely erase browser cookie information. can only be resolved temporarily

2. Check if cookies are set too much in the program

Number of Cookies limit

	IE6.0	ie7.0/8.0	Opera	Ff	Safari	Chrome
Number of cookies	20 per domain	50 per domain	30 per domain	50 per domain	No number limit	53 per domain
Cookie size	4,095 bytes	4,095 bytes	4,096 bytes	4,097 bytes	4,097 bytes	4,097 bytes
