[squid-users] Content / Message JS Injection for HTTP Pages Only

[Eliezer Croitoru]

Hey Naveen,

ECAP and ICAP been in use for such things very long ago.
This is one of the reasons for the movement in the network to encrypt
traffic and also to pin certificates in the applications.
You will need to choose to go either with ECAP or ICAP and from there the
direction is pretty simple.
I was thinking of publishing an example using an ICAP service which is based
on this example:
https://github.com/elico/icap/blob/master/example/redirect.go

But I am not sure if it would be a good idea to do so.
I believe that if you will be able to grasp the example you would be able to
mangle it a bit to act as "proxy" in a way and then to inject content into
the body of the response.
You will need some skills and experimentation with the GoLang language and
concepts to make it work.
It's not a beginner task so don't expect it to be accomplished in one week.

Let me know if you need some more guidance.

Eliezer

Subject: [squid-users] Content / Message JS Injection for HTTP Pages Only

Hello Squid Admins 
Squid 3.5 acts as HTTP Proxy only and does not allow any other kind of
Traffic 
For Such a Setup where only HTTP traffic flows through Squid 
I want to Insert a Banner / Java Script based Dynamic Page in the HTTP
response , to notify the users or alert the users based on their usage 

Would like to know how to go about the same 
Should I use ICAP or ECAP or any other suggestions ? 
Has anybody set up anything similar to this ? 
Any words of advice is welcome 

Thanks 
Naveen
