[users@httpd] How to rewrite background tag using proxy_html module

[senthil kumar <bsenthil@xxxxxxxxx>]

Hi,

I am using proxy_html module to rewrite the my html page url

html source
 <td background
="images/topbg.gif" width="34%"><img
 src="images/topband2.jpg" height="103" width=
"318"></td>

I configured rules below
PoxyHTMLURLMap ^images/(.*)$ http://127.0.0.1/agent/images/$1
 RXi
ProxyHTMLURLMap (.*) http://127.0.0.1/agent/$1 RXi

Rewritten html source
 <td
 background="images/topbg.gif" width="34%"><img
 src="http://127.0.0.1/agent/images/topband2.jpg" height
="103" width="318"></td>

I want to rewrite the 
background="images/topbg.gif 
tag  to 
http://127.0.0.1/agent/images/topbg.gif.

Please suggest your solution.

Thanks,
bsenthil.
