Appending iRule

For the first iRule, let's say your incoming URI is "/foobar". You are resetting the URI to the "/test/app.aspx /foobar". I'm assuming that isn't what you want to do. If you just want to change the URI to /test/app.aspx" then leave out your trailing [HTTP::uri] from the assignment.

You mean to remove [HTTP::uri] and make like this:

 

 

when HTTP_REQUEST {

 

if { not ([HTTP::uri] starts_with "/test") } {

 

HTTP::uri /test/app.aspx

 

}

 

}

 

 

But this gives the same results as the pictures didn’t appear.

If you just want to rewrite requests to the root document (path equals /), you could use this:

  
 when HTTP_REQUEST {  
     Check if path is /  
    if {[HTTP::path] eq "/"}{  
  
        Rewrite path to /test/app.aspx 
       HTTP::path "/test/app.aspx"  
    }  
 }  
 

If you want to prepend a string to all URIs if it's not there already, you can use a rule like this:

  
 when HTTP_REQUEST {  
     Check if path doesn't already start with /test/ 
    if { not ([HTTP::path] starts_with "/test/")}{  
  
        Rewrite path by prepending "/test/" 
       HTTP::path "/test/[HTTP::path]"  
    }  
 }  
 

Note that if you don't care about inspecting the query string it should be more efficient to modify just the path using HTTP::path.

All,

 

I have an append/redirect question.

 

Right now I am doing a straight redirect based on two different paths, but now my users want to add arguments to the paths how can I do this? Below is the current rule and an example of the url the users are trying to use.

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] equals "/dev" } {

 

log local0. "Found the uri /"

 

HTTP::redirect "https://www.server1.com:4444/dev"

 

}

 

if { [HTTP::uri] equals "/test" } {

 

log local0. "Found the uri /"

 

HTTP::redirect "https://www.server1.com:4444/test"

 

}

 

}

 

 

so basically the redirection takes you to the apache server running on 4444 instead of 443, but the question is if a user hit https://www.server1.com/test/USERNAME -or- https://www.server1.com/dev/PROJECT the redirect takes them to the mainpage (since that is what the rule tells it to do), but how can I grab the PROJECT code or the USERNAME and pass that to the redirect or append it to the redirect?

 

 

Thanks,

 

Matt

Hi Matt,

 

 

It would help if you created a new post for your question. You can parse the fields in the path using getfield:

 

 

[getfield "/path1/path2/path3" "/" 3] returns path2

 

 

So [getfield [HTTP::path] "/" 3] for a request to /test/USERNAME would return USERNAME.

 

 

If you create a new post, can you add a few examples of what you'd like the original and modified requests to look like?

 

 

Thanks,

 

Aaron
