Recently, there are some visits to my site with UserAgent "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0; LSIE 1.1.8.4)". What does the "LSIE" stand for?
LSIE is an additional information added to the UserAgent string
Usually a part of the UserAgent is used to add additional info about the used browser/machine/factory; LSIE seems to be an additional info added from BenQ-Siemens systems.
