Solution Notes
The following property has been updated with a new value (BrowserIdCacheFileNameContributor) as part of the changes for 6.2 version:

##
## Cache File Name Contributors
##

    #
    # Input a list of comma delimited class names that implement
    # com.liferay.portal.servlet.filters.util.CacheFileNameContributor.
    #
    # These classes contribute to the cache file names for static resources in
    # AggregateFilter and DynamicCSSFilter.
    #
    cache.file.name.contributors=\
        \
        #com.liferay.portal.servlet.filters.util.ColorSchemeIdCacheFileNameContributor,\
        \
        com.liferay.portal.servlet.filters.util.BrowserIdCacheFileNameContributor,\
        com.liferay.portal.servlet.filters.util.LanguageIdCacheFileNameContributor,\
        com.liferay.portal.servlet.filters.util.MinifierTypeCacheFileNameContributor,\
        com.liferay.portal.servlet.filters.util.ThemeIdCacheFileNameContributor

These contributor classes are defined in portal-impl.jar#META-INF/util-spring.xml in 7.0 version.

themes attached can be used for this purpose.
2-) Deploy this theme and use it for any page with using a browser different than IE for the first time.
3-) Open the portal from IE selector.
4-) See that portal uses the same cache which was cached for other browsers than IE.
