Hello All, I have downloaded the latest version of icap_server & squid-icap_client available in sf.net. Installed & configured to use respmod. I used bannerPl.py to insert a html tag like insert_matter = "<TABLE><tr><td><br><br>BANNER<br></td></tr></TABLE>" Example: ICAP Response Modification ICAP Request and Response [root@jasmine squid-icap]# telnet 172.16.1.192 1344 Trying 172.16.1.192... Connected to 172.16.1.192. Escape character is '^]'.

[root@jasmine squid-icap]# The problem is the value 6a (content size) is also displayed my browser. Since the ICAP protocol is designed in that way i am confused if this is the problem with squid-icap. i am in the process of debugging the problem.. Please help me in this regard. Thanks, -Senthil Murugan
