See the documentation on mod_substitute.html
I was following this thread and the doc says
"expr=" substitution values were added in 2.5.1
But my install is /2.4.38. I have installed it with brew on a Mac but I
can't find a dev version. What can I do? Must I install it from source?
Thanks in advance
Luis
<https://httpd.apache.org/docs/trunk/en/mod/mod_substitute.html>. It
describes that if you want to access environment variables, then the
substitution must begin with ‘expr=’.
The doc provides an example for substituting with variables:
*Expression Example*
<*Location*"/">
*AddOutputFilterByType*SUBSTITUTE text/html
*Substitute*"s/example.com/expr=%{HTTP:HOST}/i"
*Substitute*"s/Hello, (\S+)/expr=Hello from %{REQUEST_URI}, \$1/i"
</*Location*>
Hazarding a guess, you could try prefixing your substituted string with
‘expr=’, as follows:
*Substitute*"s|src=\"(.*?)\"|expr=src=\"%{st}e/lp/$1\"|i"
I’m just reading from the docs and have not tried it myself.

*Subject:* Help configure a Reverse proxy with Substitute
Dear community,
I need an advice on how to configure a reverse proxy in which I need to
replace the <img src=""> tag from the response html with an ENV variable
defined previously. How do you recommend me to do this?
I tried with substitute, but unfortunately doesn't seem to support
variables.
The variable I am setting with the command: SetEnvIf Request_URI
"/lp\/([a-zA-Z0-9]*)" st=$1.example.com
and now I would like to use the {st} variable in the substitute
Substitute "s|src=\"(.*?)\"|src=\"%{st}e/lp/$1\"|i"
I tried with %{st}e , ${st} in any combination it doesn't work.
Is there any way in which I can use e previous defined variable in
rewriting the proxy response HTML?
Thank you,
**
