Configuration
Avira GmbH Avira AntiVir WebGate 28
• If the option RefreshInterval is deactivated or the Client is not a
browser, (temporary) HTTP redirects are sent to the Client. Thus, the Client is
cyclically redirected to a dynamic-generated URL, intercepted by WebGate in
order to avoid the timeout. Default:
RedirectInterval 0
• The above method does not work for all Clients. When encountering prob-
lems, use the KeepaliveInterval option, to make WebGate send mes-
sages to the Client at certain intervals. The value must be smaller than the one
set in the Client or proxy server. Default:
KeepaliveInterval 30
KeepaliveMode
• If you encounter client timeout problems, because the timeout methods
described above are not appropriate in your environment or do not work prop-
erly, you may enable data trickling by setting KeepaliveMode in
avwebgate.conf to trickle. If this method is used, WebGate sends small
pieces of the data at the specified KeepaliveInterval, until the download
and scan is complete. Once the file is downloaded and scanned, the remainder
of the file will be immediately transferred to the client (if clean).
HTTPProxy...
Settings for HTTP proxy server:
These settings work only for Network Configuration 1. For the installation before
a proxy server, WebGate needs the following information:
• HTTPProxyServer: Name or IP address of the proxy server
• HTTPProxyPort: The port for the proxy server
• HTTPProxyUsername,HTTPProxyPassword: Login and password for
proxy server, if needed
Example:
HTTPProxyServer [hostname|ip]
HTTPProxyPort 3128
HTTPProxyUsername username
HTTPProxyPassword password
FTPProxy...
Settings for FTP proxy server:
If WebGate serves as FTP proxy (see FTPPort option), you can set a parent proxy
for FTP connections. Example:
FTPProxyServer NONE
FTPProxyPort 2121
Temporary
Dir
Temporary directory:
You can change the name of the temporary directory. The standard is /tmp. This
It is NOT recommended to enable data trickling unless you are experiencing problems
using the other timeout prevention methods. Be aware of the risks and limitations before
you enable this feature. In MANUAL.avwebgate under "Client Timeout Prevention", you
can find more details about related parameters, limitations and about setting domain/
file type rules.
