I don\'t want the browser to cache a specified jsp, so I used the code below in my jsp:
<% response.setHeader(\"Pragma\", \"No-cache\"); response.
A typo? Pramga instead of Pragma? Try.
Pramga
<% response.setHeader("Pragma", "No-cache"); response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); response.setDateHeader("Expires", -1); %>
EDIT: see this question How to control web page caching, across all browsers?
