Hi All,

I’m working on this requirement to rewrite the URI path in the HTTP Request, just the URI path and not the query portion.

E.g.

Incoming request to

http://1.1.1.1/test/abc?param=1234567890

should be translate to when sending to backend.

https://2.2.2.2/test/abc1?param=1234567890

I’ve tried few iterations but none have worked for me so far.

Sample1

when HTTP_REQUEST {

if { [HTTP::uri] starts_with “/abc1?/” } {

HTTP::uri [string map {“/abc1?/” “/abc2?/”} [HTTP::uri]]

}

}

Sample2

when HTTP_REQUEST {

if {[HTTP::uri] contains “test/abc?param=” } {

set newURI [string map {“test/abc?param=” “”} [HTTP::uri]]

HTTP::uri /test/abc1?param=

}

Hi,

for request “http://1.1.1.1/test/abc?param=1234567890”

host  : 1.1.1.1
uri   : /test/abc?param=1234567890
path  : /test/abc
query : param=1234567890

If you want to change the host, you can use HTTP::redirect

Sample

Request: http://1.1.1.1/test/abc?param=1234567890

Redirect: https://2.2.2.2/test/abc2?param=1234567890

when HTTP_REQUEST {
	if { [HTTP::path] equals "/test/abc" } {
		set newUri [string map {"abc" "abc1"} [HTTP::path]]
		HTTP::redirect "https://2.2.2.2$newUri?[HTTP::query]"
	}
}

Hi,

Here 1.1.1.1 is the VIP and 2.2.2.2 is the backend server.

In original case Host header will be name as it is.
