WebShield and WebWasher - incomplete loading of pages

Avast Free Antivirus / Premium Security
1

I seem to have some problems with WebShield making IE (on XP Pro SP2) loading some HTTP or HTTPS pages incompletely.

I use WebWsher to clean web pages and have IE set up to use automatic proxy configuration:

http://127.0.0.1:8080/proxyconf

I am not sure wether I need to re-configure WebShield to redirect port 8080 traffic.

Interesting. I reckon your current setup (with no reconfiguration) has to work the following way

browser → WebWasher → WebShield → Internet

because WebShield is only filtering traffic on port 80 and this is what WebWasher is using to get the data from the servers.
You could try to configure it like this:

browser → WebShield → WebWasher → Internet

which would require you to set up things manually. Please see my instructions on how to do this here: http://forum.avast.com/index.php?topic=11294.0 (in this case, address_of_your_proxy_server is probably localhost (or 127.0.0.1, which is the same).

You mean I should do something like this:

configuration required for:
browser → WebShield → WebWasher → Internet

  1. WebShield:
    Redirected HTTP ports: 80

  2. avast4.ini:
    [WebScanner]
    UpstreamProxyHost=127.0.0.1
    UpstreamProxyPort=8080

  3. IE LAN settings:

I think in this case you must remove the checkmark from automatic configuration script…

  1. What’s in the http://127.0.0.1:8080/proxyconf in your case?
  2. You should also remove the “80” from the redirected ports. Otherwise, the WebShield would also be picking stuff that your proxy will be downloading from the Internet (browser → WebShield → proxy → WebShield → Internet).

content of proxyconf is simple function to make sure only http traffic is gouing through proxy:

function FindProxyForURL(url,host)
{if(url.substring(0,5)==“http:”)
return"PROXY 127.0.0.1:8080";
return"DIRECT";}

could you please post the configuration you suggest in detail (I’m not sure I do understand exactly what you mean)?

This is what I meant (and uncheck the automatic configuration script option.

vlk,

i’m really confused here. please look at the attached webwasher proxy config screen and tell me what additional settings are required in avast.

No, not really. :slight_smile:

  1. Configure the browser as displayed in my post above
  2. configure WebShield to use WebWasher as an upstream proxy (as shown above, by editing avast4.ini)
  3. disable redirection of port 80 in WebShield
  4. tell WebWasher NOT to use any proxy server.

Thanks

but: on my xp pro systems there are always severel user accounts. some accounts will utilize webwasher while others won’t. doesn’t your suggestion imply that users who don’t use webwasher and those who use it need different settings for the webshield and avast! ini file? that would be a hardly managable situation.

  • i need a “generic” setup here, otherwise webshield is pretty useless for me.

Well the fact is, WebShield should work with WebWasher quite easily even without a reconfig, I just wanted to find out if settings the things up manually solves the problem…

This will probably not be a final solution (if you have a multi-user scenario here) but I’d still like to know if it works this way.

Thanks :slight_smile:
