The HTTP Proxy is a module built into the RouteFinder to redirect HTTP
requests from the clients in the LAN and DMZ to the Internet. The HTTP
proxy acts as a caching server for web clients, supporting FTP, gopher,
and HTTP data objects. Unlike traditional caching software the HTTP proxy
keeps meta data and especially hot objects cached in RAM and also caches
DNS lookup.
Note : To view/analyze the HTTP proxy logs through WebTrends software,
HTTP access has to be enabled in the Administration->Web Admin page and
the port number configured for HTTP access has to be used.
If enabled the HTTP proxy functions as a transparent proxy. The web clients
are unaware that their requests are being transferred through a HTTP Proxy.
The web clients need not configure their browser to point to the Proxy
server. Also, in the browser settings the HTTP port is configured
to port 80 - the default port for the HTTP protocol.
If disabled the HTTP proxy functions as a non-transparent proxy. The
browser settings of web clients must be such that they point to the HTTP
Proxy, and the HTTP port number must be set to the port on which the HTTP
proxy listens to requests. The default port is 3128.
HTTP Proxy - Networks (allowed / denied)
Defines the allowed / denied status for a network / host for access to
the HTTP proxy. On clicking the 'Edit' button a list of the defined networks/hosts
and the current status is displayed. The status can be changed by clicking
the change status option and altering the policy as desired.
HTTP Proxy - Banner Filter
If enabled, all the banners in the web pages are filtered out before the
page is forwarded to the web client.
HTTP Proxy - Java Script Filter
If enabled all the Java Script components in the web pages are filtered
out before the page is forwarded to the web client.
HTTP Proxy - Cookie Filter
If enabled cookies in the web pages are filtered out before the page is
forwarded to the web client.
URL Categorization - URL Filter
If enabled, traffic from defferent URLs can be configured to be filtered
/ forwarded by the RouteFinder based on their categories.
URL Categorization - URL Categories
Clicking on the edit button allows configuration of the URL categories
to be filtered or forwarded.
URL Categorization - Networks / Hosts to bypass
URL Filtering
Clicking on the edit button allows configuration of the networks / hosts
for which URL Category based filtering will not happen. These networks/hosts
will be able to access all sites.
Authentication - User Authentication Status
Used to enable / disable User Authentication. If User Authentication is
disabled then the HTTP proxy can be configured to function in the
transparent mode.
Authentication - Authentication Types
If the HTTP proxy functions in a non-transparent mode then the authentication
mechanism through which user can be authenticated, can be configured. The
different authentication types are local, RADIUS and SAM. The user can
configure any one of the three types. The authentication types can be added
by selecting the type from the selection menu and clicking the 'Save'
button.
Authentication - Add / Delete Users
A list of users who are allowed to access the HTTP Proxy can be configured
by selecting the users from the 'Available Users' list and clicking the
'Add' button.
Note: These users can also be added by checking the checkbox against
HTTP users in the 'Users"' menu of the 'User Authentication' section.
The users who currently have HTTP access can be denied access by selecting
the users to be deined acces from the 'Allowed Users' list and clicking
on the 'Delete' button.
The 'Allowed Users' list consists of the local users who are allowed HTTP
access and the 'Availlable Users' list consists of the local users who
are not allowed HTTP access.
