Hi All,
I have a JSP which contains a form , when the form is submitted the control comes to servlet . this is working fine in IE. but in google chrome it going to error page . When i debugged from the develper tools , i found one difference , the form in IE is had "= " but in chrome had ":"

example :
IE -- >
UpdateAll=UpdateAll
pf_hp=1

chrome -->

UpdateAll:UpdateAll
pf_hp:1

is this the reason for error ???
i can paste the whole jsp but it is very big .
