Content Rewrite rule

I have been fighting with content rewrite rules and 90% of my site is being re-written, but there are a few perma links that are not, and as a result, I get mixed content warnings.

The basic content rewrite I lifted off of a devcentral article, see below. However, when the content contains:

"http:\/\/www.sitename.com\/sub\/sub\/\", it is bypassed and not translated. I have tried changing the stream expression from STREAM::expression {@http://@https://@} to STREAM::expression {@http:@https:@} and also STREAM::expression {@http:\/\/@https:\/\/@}, but it is still bypassed.

# Example which replaces http:// with https:// in response content

# Prevents server compression in responses

when HTTP_REQUEST {

  # Disable the stream filter for all requests

  STREAM::disable

  # LTM does not uncompress response content, so if the server has compression enabled

  # and it cannot be disabled on the server, we can prevent the server from 

  # sending a compressed response by removing the compression offerings from the client

  HTTP::header remove "Accept-Encoding"

}

when HTTP_RESPONSE {

  # Check if response type is text

  if {[HTTP::header value Content-Type] contains "text"}{

   # Replace http:// with https://

   STREAM::expression {@http://@https://@}

   # Enable the stream filter for this response only

   STREAM::enable

  }

}
