Invalid action EV_INGRESS_DATA during ST_HTTP_PREPEND_HEADERS

Thanks. I checked that one out too, and that KB update does not apply to the IIS boxes we are using. The service pack already covers it. Could the content length be changed if i am doing a header insert in the http profile? It's strange that it only shows up on the SSL profiles, not the regular http profiles. I'll hit up F5 and see what they think.
