Available Filters

Filter implementations for a number of well-known proxies are provided by and can be requested from unblu in binary or source code form (see below). This includes: native filter (C source code package); typically used for OEM integrations with proxy providers.

Note: F5 BIG-IP is not supported. If you already use F5 please talk to us about it.

In addition, the following proxies feature Filter integrations provided by unblu and / or the proxy distributor:

Reverse Proxy Integration (Optional)

unblu can be used with or without a reverse proxy but there are a number of general benefits to using a reverse proxy such as load balancing and security, and it allows you to remove the need for direct access to your servers.

The main benefit of integrating a reverse proxy, in the case of the unblu product, is that it allows you to use the Filter. The Filter can be used inside the filter chain of a reverse proxy to inject the snippet dynamically and accommodate co-browsing-specific communication automatically.

In cases where capture and secure resources are of particular importance, the filter integration is recommended. Using the filter means that all resources will come from the server and that everything is uploaded by the filter. See Architecture with the Filter. (Depending on your current setup, using the filter can harden your system by reducing the 'attack surface'.)
