Jboss and Apache Cache Issue

imranbaseer Oct 11, 2012 10:55 AM

I have deleted the old PDF file of the Web Server at Application side and I uploaded a new PDF file ( file name is the same ).

Whenever I open the file, the old file keeps being opened.

We restarted Jboss and Apache, deleted Browser history and had also Ctrl+F5 etc . but the result did not change.

When we check it from Network area the new PDF file could be opened.

From new client PC ( more than a week) , the old PDF file is displayed,

I have checked yesterday and we could refer to the new PDF file.

Would you please let us know, what could be reason for above issue?

You can try so:

Add this string when you call the udl pdf ?pippo

example

http://localhost/mysite/dowanlod/my.pdf

you have call

http://localhost/mysite/dowanlod/my.pdf?pippo

Into your broswer you use an Proxy?

The new files are displayed if we add ? after the correct URL.
Could you please let us know, how could we open the new files without putting ? after the correct URL.

OK try this:

Enable mod_headers on apache (LoadModule), then add tih to your httpd.conf file:

<filesMatch "\.(pdf|txt|doc|exe)$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>
</filesMatch>
