Re: [squid-users] NEW:Re: [squid-users] Banner

Alireza,


In the past, our proxy pac would pop up warning page about
correct internet usage. But that was annonying and removed.

And you have received the slightly obfuscated answer "this is not the
job of Squid".

You have two choices:

   a) Make your users install and use your custom made browser who
includes such banners. (most likely the easiest approach)

   b) Write a content transforming proxy who adds such banner by clever
rewriting of returned HTML. Quite many sites are likely to fail when
accessed via such proxy.


Writing a prototype proxy doing 'b' is simple. Writing one that actually
works to a acceptable level is a nightmare and requires detailed
knowledge of programming, HTML, Dom, JavaScript and VBScript, as all
levels need to be adjusted to account for the banner added..

Complications for a rewriting proxy adding banner:

   * Frames. The proxy do not know if a page is displayed in a frameset
or not.

   * DOM. If you change the HTML layout then this may have effects on the
DOM layout as well unless done carefully.

   * JavaScript/VBScripts. Care must be taken not to disturb
JavaScript/VBScript snippets running on the pages..

   * HTML Layout.

   * CSS layout.

   And probably many more.

Regards
Henrik
