Simple iRule for URL appending?

This is a simple version that will do the initial redirect.

when HTTP_REQUEST {
if { [HTTP::path] equals "/" } {
HTTP::redirect "/somewhere/else.html"
}
}

Let us know if this takes care of what you need or if you need anything else.

Most Excellent!!! Worked like a charm. Thanks.

This is a simple version that does what you are describing that you need.

 
when HTTP_REQUEST {
if { [HTTP::path] equals "/" } {
HTTP::redirect "/somewhere/else.html"
}
}

If you are needing something in addition to this or different functionality let us know.

Keep in mind that HTTP::redirect issues a 302 - temporary redirect. It's more efficient to use 301s (permanent redirect) since it's cached by the client.

 

 

If you're pretty certain that the redirect target is not likely to change I'd use a 301. Otherwise you'll want to stick with a 302.

 

I have an very similar request which is that instead of append uri after url, I need insert "/aaa/bbb" in between. e.g. when user type in "http://www.testdomain.com/*", my F5 iRule need insert /aaa/bbb/ and make it "http://www.testdomain.com/aaa/bbb/*". Looking forward your kindly reply.

 

 

Not sure if "*" is the correct wildcard in TCL scripting, but when I put in "*", I actually mean that user could be puting different value.

 

 

Thanks

Then you'd want something like:

when HTTP_REQUEST {
  if {!([HTTP::uri] starts_with "/aaa/bbb")} {
    HTTP::redirect "http://www.testdomain.com/aaa/bbb[HTTP::uri]"
  }
}

yes, this is what I put in right now:

 

 

when HTTP_REQUEST {

 

if {[HTTP::path] matches_regex "/*"} {

 

HTTP::redirect "/aaa/bbb[HTTP::uri]"

 

}

 

}

 

 

I did a packet capture on the VIP and by follow TCP stream, I find this iRule will insert /aaa/bbb with every HTTP request dose not matter it have /aaa/bbb or not. It will just insert /aaa/bbb over and over without stop, so the HTTP GET becomes....

 

 

 

1. GET /aaa/bbb/test.html

 

2. GET /aaa/bbb/aaa/bbb/test.html

 

3. GET /aaa/bbb/aaa/bbb/aaa/bbb/test.html

 

............

 

............

 

n. GET /aaa/bbb/aaa/bbb/...................................../aaa/bbb/aaa/bbb/test.html

 

 

Is there anything I can do in this iRule to make it insert only once?

 

 

Thanks

The rule I wrote earlier does that check. The line that's important is:

if {!([HTTP::uri] starts_with "/aaa/bbb")} {

This means that the redirect only occurs if the URI doesn't already start with "/aaa/bbb"

I'm glad you got it working. :)

Hey guys,

This iRule works perfectly for me:

when HTTP_REQUEST {
if { [HTTP::path] equals "/" } {
HTTP::redirect "/apath"
}
}
 

But before using it I tried the following and it didn't work but I still have the curiosity to know why if anyone has any idea why please let me know. Here's my iRule:

 when HTTP_REQUEST {
set val [HTTP::uri]
if { {[string length $val] == 0} or {[string length $val] == 1} } {
HTTP::redirect https://[HTTP::host]/apath
}
}
