Occasionally, users see chunk boundaries as part of HTTP response if the virtual server is configured with rewrite profile variant and some other profiles.
End users may see random characters displayed on their web pages, or the page may fail to render because it contains invalid HTML markup.
Virtual server with rewrite profile variant and some other profiles like OneConnect and NTLM could cause HTTP response to be double-chunked.
To workaround this problem, use an iRule to rechunk the HTTP response always.
Simple iRule is added inside code to rechunk the response in HTTP_RESPONSE event when the content is already chunked by backend/application servers.
