F5 iRule to get data group address content values list

I am now using two v. servers. The front one uses a stream profile and this iRule:

when HTTP_REQUEST {
    HTTP::header remove Accept-Encoding
    STREAM::disable
    virtual vs_ipv4feed_client_http
    return
}
 
when HTTP_RESPONSE {
    set find " "
    set replace "</br>"
    STREAM::expression "@$find@$replace@"
    STREAM::enable
}

The backend v. server (vs_ipv4feed_client_http) uses the iRule I pasted in the previous post as well.

when HTTP_REQUEST {
	switch -glob [string tolower [HTTP::uri]] {
    "/azureipv4.txt" {
       # Retrieve the Azure datagroup contents, send it in a HTTP 200 response
	   HTTP::respond 200 content [class names azure_ipv4_dg] "Content-Type" "text/html"
       }
    }
}

The output looks like this now:

102.133.0.0/18

102.133.112.0/28

102.133.120.0/21

102.133.128.0/18

102.133.192.0/19

102.133.224.0/20

102.133.240.0/25

102.133.240.128/26

102.133.248.0/21

102.133.64.0/19

....

Which is what I wanted. However, if I look a the source code of this txt file within the browser, it looks like this:

102.133.0.0/18</br>102.133.112.0/28</br>102.133.120.0/21</br>102.133.128.0/18</br>102.133.192.0/19</br>102.133.224.0/20</br>102.133.240.0/25</br>102.133.240.128/26</br>102.133.248.0/21</br>102.133.64.0/19</br>102.133.96.0/20</br>102.37.0.0/20</br>102.37.128.0/19</br>.......

My problem is that the firewall that I need to feed this list within, expects a native txt file with line breaks, rather than an html based txt file which uses "</br>". Therefore, I am unable to feed those IPs into my firewall, unless I somehow present this txt file as a native txt.
