Explaination on the iRule

Hi MOHIT,

the iRule will check an incoming request for the URI (

/path?query

) for a trailing slash (

/

).

In case of a match it will remove all trailing slashes and redirect the client to the initial host and modified URI as follows:

 curl -I 'http://10.131.131.102/test/'
HTTP/1.0 302 Found
Location: http://10.131.131.102/test
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

In the example above the URI ends with a (

/

) and the client will be redirected as indicated by the location header in the response.

 curl -I 'http://10.131.131.102/test'
HTTP/1.0 200 OK
Server: LB-NET
Set-Cookie: JSESSIONID=427398920.293652780
Set-Cookie: StaticCookie=lb-net_static
Connection: close
Content-Length: 1016

In the second request the URI does not contain the trailing (

/

) and the requested object will be served.

To avoid a continuous loop (default requests will be of "/" and ends with a (

/

) as well I recommend to change the iRule as follows:

when HTTP_REQUEST {
    if { ([string tolower [HTTP::uri]] ends_with "/") and not ([HTTP::uri] equals "/") } {
        HTTP::redirect http://[HTTP::host][string trimright [HTTP::uri] "/"]
    }
}

You may also consider, to verify the

[HTTP::path]

only.

Thanks, Stephan

string trimright

" command.
