Here problem is with

(Hash). Its not a fault of your iRule or even F5 policy, its more of the underlying HTTP standard. That is the reason F5 policy or iRule will not allow you to save.

In the URI world the Hash-Sign () is called a "Fragment" and is completely suppressed from sending by every browser.

In-fact, everything after the Hash-Sign never initiate connection and therefor never reaches your F5.

    Is there any way to use a string variable to circumvent the above problem? Or does anyone have any other solutions?

    Tried to manipulate string variable in iRule. You can try some thing like this, if above incoming & outgoing url is same.

    Hope will work.

        when HTTP_REQUEST {
    set url [string range [HTTP::uri] 12 end]
    log local0. “URI: $url”
    HTTP::redirect "https://www.mydomain.com/Data$url"
    }
