write the program for uploading files in java. There is no problem with deployment on other servers in Aliyun.
but after deployment in the customer"s own server room, my visit to the upload page IE11 reports the following error
SCRIPT7002: XMLHttpRequest: network error 0x2eff. this operation cannot be completed due to error 00002eff.

other Firefox 360 also reported upload failure, but there was no error message as above.
