Pool can not select pool member for POST from IE 11

Hi, now we are running into a strange trouble with IE 11 that posts a form containing file uploading. In the iRules associated with HTTP_REQUEST, we call pool to forward all incoming HTTP Requests, including POST to Web-app in Openshift environment that consists of two pool members (active all the time):

                SSL::enable serverside
                pool openshift3_infra

To post a form that doesn't contain file uploading, it works perfectly. However, while posting a form that contains file uploading, after calling "pool openshift3_infra", it seems that BigIP just stops there, neither LB_SELECTED nor LB_FAILED is triggered. In the end, IE just displays "Internet Explorer can not display web page"

It's really appreciated if someone could shed the light on it and you'll be my life-saver 🙂

Thanks in advance!

    Unless you are using oneconnect or LB:detach, a load balancing decision will only be triggered once per connection. So, events about load balancing decision only ocurs once per connection.

     

    Use HTTPWatch, Fiddler, or something similar, to capture what happens when transferring files. What URL the browser is trying to send the traffic. Also, check if you go directly to one of the servers the transfer works.
