HTTP Request Policy
HTTP request policies allow manipulation of HTTP requests. These requests may be modified before they are forwarded to the server, used as a basis for content switching, or discarded. The HTTP request policies may only be applied to a layer 7 virtual service configured with an HTTP profile. The table below lists the match criteria available under HTTP request, as well as the actions that can be configured to occur upon a match being made.
|Match||Client IP: Client IP address or a group of client addresses.
|Service Port: The ports the virtual service is listening on.|
|Protocol Type: HTTP or HTTPS.
|HTTP Method: The method used by the client request. The match is true if any one of the methods that an administrator specifies is true.|
|HTTP Version: True if the client version is .9, 1.0, or 1.1|
|Path: The path or a group of paths. Paths start with a ‘/’ (for example, /index.html</b>?a=1&b=2).
|Query: A query or a group of queries. Do not add the leading ‘?’ or ‘&’ characters to a match.
|Headers: True if a header exists, or if it exists and contains a specified value|
|Cookie: True if a cookie exists, or if it exists and contains a specified value|
|Host Header: The request’s host header.
|Actions||Logging: Selecting the logging checkbox causes Avi Vantage to log when an action has been invoked.|
|Redirect URL: Redirects a client to a different protocol, port, host, or path. By default the host, path, and query are not altered unless an administrator populates those fields. The path field does not require a leading “/” slash character. To create a simple HTTP to HTTPS redirect, simply set the protocol to HTTPS. NOTE: The redirect action may not be stacked with other actions.|
|Modify Header: Allows adding, replacing, or removing of an HTTP header or cookie.|
|Rewrite URL: Similar to ProxyPass functionality, this action allows for the client’s requested URL to be rewritten into a URL that the server understands. For instance, the client should usewww.avinetworks.com/sales, while the server may be configured for sales.avinetworks.com. The path field does not require a leading "/" slash character.|
|Content Switch: Forward matched requests to a pool, or a specific server with that pool. Alternatively, Avi Vantage can serve an HTTP response using HTTP status code 200 (success), 403 (unauthorized), 404 (file not found), or 429 (too many requests). A default page is sent for each of these status codes, or a custom html file may uploaded.|
