mod_substitute provides a mechanism to perform both regular expression and fixed string substitutions on response bodies.

Substitute Directive

Description:	Pattern to filter the response content
Syntax:	`Substitute s/pattern/substitution/[infq]`
Context:	directory, .htaccess
Override:	FileInfo
Status:	Extension
Module:	mod_substitute

The Substitute directive specifies a search and replace pattern to apply to the response body.

The meaning of the pattern can be modified by using any combination of these flags:

i: Perform a case-insensitive match.
n: By default the pattern is treated as a regular expression. Using the n flag forces the pattern to be treated as a fixed string.
f: The f flag causes mod_substitute to flatten the result of a substitution allowing for later substitutions to take place on the boundary of this one. This is the default.
q: The q flag causes mod_substitute to not flatten the buckets after each substitution. This can result in much faster response and a decrease in memory utilization, but should only be used if there is no possibility that the result of one substitution will ever match a pattern or regex of a subsequent one.

<Location /> AddOutputFilterByType SUBSTITUTE text/html Substitute s/foo/bar/ni </Location>

If either the pattern or the substitution contain a slash character then an alternative delimiter should be used:

<Location /> AddOutputFilterByType SUBSTITUTE text/html Substitute "s|<BR */?>|<br />|i" </Location>
