Apache Module mod_substitute
Summary
mod_substitute provides a mechanism to perform
both regular expression and fixed string substitutions on
response bodies.
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.
Example
<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:
Example of using an alternate delimiter
<Location />
AddOutputFilterByType SUBSTITUTE text/html
Substitute "s|<BR */?>|<br />|i"
</Location>
