[o.a.c.h.Http11Processor] Error Parsing HTTP Request Header: Invalid Method Name

This error occurs when the HTTP request header contains an invalid character in the method name. HTTP method names must be tokens, which means they can only contain letters, digits, and a few special characters such as hyphens and underscores.

To resolve this error, you need to check the HTTP request header and ensure that the method name is valid. If you are using a third-party library or framework to handle HTTP requests, you may need to consult its documentation to see if there are any specific requirements for the method name.

In some cases, this error may be caused by a malicious client sending a malformed request. If you suspect this is the case, you may want to implement additional security measures such as rate limiting or input validation to prevent such attacks.
