Subject Re: Browser cookie and Apache server calls
Date Thu, 27 Jun 2013 04:28:33 GMT
If I clear the browser cache before I click on the hyperlink, I dont see
this issue. But I do not want to delete the cookies, because the business
logic used by the filter makes use of the cookies that are set. Also I may
not want to delete the cache everytime before I click on the hyperlink :(

I added the below lines in httpd.conf file but still see that the page is
cached and hence no server call is made :(
LoadModule headers_module modules/
Header set Cache-Control "must-revalidate, no-cache"
