Fileupload problem

I am new to BigIP. I am load balancing two servers both running java servlet / jsp applications. Some of the 3rd party modules are hosted in iframes and to get the content it uses a non relative url. The application as a whole needs to use https. So I created this irule.

 

 

when HTTP_REQUEST {

 

HTTP::redirect https://[HTTP::host][HTTP::uri]

 

}

 

 

But now I am getting the unintended consequence that fileuploads are working sometimes and not other times. It is not a file size issue. It happens in Firefox and IE8. This is the error message I am getting.HTTP Status 501 - Method 240776-- GET is not defined in RFC 2068 and is not supported by the Servlet API

type Status report

 

messageMethod 240776-- GET is not defined in RFC 2068 and is not supported by the Servlet API

 

descriptionThe server does not support the functionality needed to fulfill this request (Method 240776-- GET is not defined in RFC 2068 and is not supported by the Servlet API ).

 

Apache Tomcat/5.5.29

 

 

When I go directly to the Tomcat server (skip the load balancer) and upload the same file I do not get an error and it uploads quickly. This does not happen for every file. But I have not yet noticed the common denominator in the files that is causing the issue. Most files upload fine. I do have one that consistently throws this error that is useful for debugging.

 

 

These applications ran for a while before the BigIP appliance was installed and never had this issue. So I am concerned that the problem lies with my iRule. Any suggestions on how to go about solving this issue? A better way to do the https redirect for the iframe content or a way of logging these events so I can perhaps notice a pattern in what kind of files are causing the issue or a way to redirect file uploads so they will work.
