HTTP has no requirement that the connecting client have reverse DNS 
setup.  Some servers have reverse lookups enabled, and some of those 
undoubtedly block until the record has been retrieved or all avenues of 
discovery have been exhausted... and this is likely where the issue 
exists.  As to why the server or the script/application its running 
needs the record, you'd have to ask the developer.
