Example: Inserting & deleting body text

Rewriting & redirecting : Example: Inserting & deleting body text

Example.com wants to delete some text, and insert other text. As an example, it wants to change:

Hey everyone, this works!

to:

Hey, this works now!

To do this, it will rewrite matching parts of the body in the web server’s response.

The regular expression contains capture groups (.*) that create numbered substrings — back-references such as $0 — that you can recall by their number when writing the replacement text. By omitting a capture group (in this case, $1 is omitted from Replacement), that part of the text is removed. To insert text, simply add it to the replacement text.
