What is HTTP_AAE?

HTTP_AAE likely refers to the 'Accept-Encoding' HTTP header, specifically requesting the server to encode the response using the 'AAE' algorithm, which is not a standard or widely recognized encoding algorithm. The Accept-Encoding header is used by clients to indicate which content encoding schemes they are able to understand. Common encodings include gzip, deflate, and br (Brotli). The server can then select one of the listed encodings and indicate its choice in the Content-Encoding response header. If 'AAE' were a valid encoding understood by both client and server (hypothetically), it could be used to compress the response body, reducing the amount of data transmitted. However, since 'AAE' is not a standard encoding, using it would likely result in errors.
