import rewrite;

Varnish vmod hack demonstrating how to rewrite HTML content. It's not production-ready - I'm still learning and looking for the best way how to do it.

Buy me a drink!

Prototype

rewrite_re(STRING SEARCH_REGEX, STRING REPLACEMENT)

Return value

VOID

Description

Rewrites all parts of document matching SEARCH_REGEX with REPLACEMENT

Usage:

./configure VARNISHSRC=DIR [VMODDIR=DIR]

VARNISHSRC is the directory of the Varnish source tree for which to compile your vmod. Both the VARNISHSRC and VARNISHSRC/include will be added to the include search paths for your module.

Optionally you can also set the vmod install directory by adding VMODDIR=DIR (defaults to the pkg-config discovered directory from your Varnish installation).

Make targets:

• make - builds the vmod
• make install - installs your vmod in VMODDIR

In your VCL you could then use this vmod along the following lines:

import rewrite;

sub vcl_deliver {
        rewrite.rewrite_re("https://www.paypal.com/cgi-bin/webscr\?cmd=_donations&business=[^&]+&", "https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=FUPUJSJ9KCPAL&");
}

(No I'm not that evil)
