Explanation
BIG-IP offers many features that you can use in order to intelligently manage your application layer traffic. These features include the ability to insert headers into HTTP requests, and the compression of HTTP server replies.
These features can be accessed through different configuration profiles. A profile is a collection of settings that correspond to HTTP traffic. A profile is a way for the BIG-IP system manage HTTP traffic.
You can use any one of these profiles to manage HTTP traffic:
HTTP (Hypertext Transfer Protocol)
HTTP Compression
Web Acceleration
General HTTP properties
You can set up a few settings to create a basic HTTP profile that uses most of these default settings.
Parent profile
Every profile you create is derived directly from a parent profile. You can either use the default http profile to create your profile or use an existing HTTP profile.
Configure HTTP
You can create an HTTP profile using a variety of settings.
Basic Auth Realm
The Basic Auth Realm setting allows you to enter a quoted string for basic authentication realm. This string is sent to clients by BIG-IP when authorization fails.
Fallback host
HTTP redirection is another feature you can set up within an HTTP profile. HTTP redirection is a feature that allows you to redirect HTTP traffic from one protocol identifier to another, host name, port number or URI path. This can be done if all members of the target pool are unavailable or if a select pool member is unavailable. The term unavailable refers a member being disabled, marked down, or having exceeded its connection limit. If one or more members of a pool are unavailable, the BIGIP system can redirect the HTTP response to the fallback host with the HTTP reply status Code 302 Found. However, redirection can also occur when an LB_FAILED iRule events is generated.
You can specify an IP address (or a fully qualified domain name (FQDN) when configuring BIG-IP to redirect HTTP traffic towards a fallback host. The value you specify will be used to determine the location header that the server will use in its response. You can, for example, specify a redirection.
