Logging "before" & "after" values is the recommended troubleshooting approach for failed replacement operations.

Give this a shot:

when HTTP_REQUEST {

  if {[string tolower [HTTP::uri]] contains ".osp" }{
     replace .ospx w/ .aspx & .osp w/ .asp
    set uri [string map -nocase {.ospx .aspx .osp .asp} $uri]
    log local0. "URI after: $uri"
     re-write post replacement URI
    HTTP::uri $uri
  }
}

That should make it more obvious whether the string map is replacing as expected.
