I have this test in a .CONF file:
| Code: | RewriteEngine on
<Location "/">
RewriteRule ^ - [E=foo:bar]
AddOutputFilterByType SUBSTITUTE text/html
Substitute "s/body/BODY/i"
</Location> |
And I'm using this basic PHP script to see the results:
| Code: | <?php
echo <<<EOF
<html>
<head>
<title>Test</title>
</head>
<body>
<pre>
EOF;
print_r($_SERVER);
echo <<<EOF
</pre>
</body>
</html>
EOF;
?> |
I see that $_SERVER['foo'] equals "bar", so the configuration is working properly and <Location> is matching. But "body" isn't being replaced with "BODY".
I'm using Apache 2.4.59, and EasyApache (via WHM) definitely shows that mod_substitute is installed. And I would assume that, if it wasn't, I would get an error when I rebuild Apache.
I double checked using Google's Dev Tools > Network > Name > Response Headers, and "Content-Type" shows:
text/html; charset=UTF-8
I'm running out of ideas! LOL Any other thoughts on why it's not substituting as expected? |

I can't reproduce your problem in a minimal test environment (Apache 2.4.59); the substitute works for me.
Using your configuration (without the PHP backend), whilst changing BODY to BoDy, viz:
| Code: | <Location "/">
RewriteRule ^ - [E=foo:bar]
AddOutputFilterByType SUBSTITUTE text/html
Substitute "s/body/BoDy/i"
</Location> |
when I access the site root and get the default "It works!" page, browser Dev Tools show the following raw response:
| Code: | | <html><BoDy><h1>It works!</h1></BoDy></html> |
In the past I have had problems with AddOutputFilterByType, with various media types, particularly when using more than one filter, e.g. substitute and compression. As a result I switched to using filter directives, not least of which you can select the FilterProvider using regular expressions; for example the following substitute filter matches a range of content types substrings:
| Code: | FilterDeclare Replace
FilterProvider Replace Substitute "%{CONTENT_TYPE} =~ m#^text/(css|html|javascript|plain|xml)#i"
FilterProtocol Replace change=yes
FilterChain +Replace |
Thereafter you declare the substitute directive as before (less the AddOutputFilterByType):
| Code: | <Location "/">
RewriteRule ^ - [E=foo:bar]
Substitute "s/body/BoDy/i"
</Location> |
Accepting this revised approach is more complicated, depending on the rest of your configuration, it may work for you. |
