BAD Request - Invalid verb , HTTP Error 400. The request verb is invalid

  1. Sometime we are getting below error while accessing the URL

BAD Request - Invalid verb , HTTP Error 400. The request verb is invalid

 

  1. Web server is IIS server , AS per Microsoft it is happening because clients are making a call to the invalid url, they can see the request is coming to http://www.bharti-axalife.com:80/https:/www.bharti-axalife.com/ but the actual URL is

https://www.bharti-axalife.com/

 

  1. Users are entering the correct URL - https://www.bharti-axalife.com/ , is this problem with F% LB or The application code ?

    Hello,

     

    It looks like it's related to the client app. If you add custom rules on the F5 LB, you may also impact the url before sending it to the server.

     

    Check your irules, then check the client side.
