Using iruel for redirects

Sure, then, that's pretty straightforward:

Create a class list containing your request and redirect details in 2 columns, separated by a space -- hostname/firstdir in one, then the redirect target in the other.

class myRedirects {
  "www.thermo.com/histology http://www.thermo.com/.../0,2152,53,00.html"
  "www.whatever.com/dir1 http://newhost/newuri"
}

Then create this iRule an apply to the virtual server:

rule URIredirects {
  when HTTP_REQUEST {
    set req "[HTTP::host]/[getfield [HTTP::uri] "/" 2]"
    set redir [findclass $req $::myRedirects]
    if {$redir !=""}{
      HTTP::redirect $redir
    }
  }
}
