Re: Clearing Browser cache for upadated deployments

[darkflame]

Remember if using crome with the inspector open, holding down the
reload button gives a option to clear cache/hard reload.
VERY usefull, yet hidden feature.

Re: Clearing Browser cache for upadated deployments

[jhulford]

If that works then it sounds like you don't have caching set up
correctly for the *.nocache.js files.  The browser shouldn't be
caching these files at all, to enforce that you'll have to send the
correct response header ("Cache-Control: no-cache, no-store") when
handling the request for those files.

Hi matthew,

Thats a very good approach I like that. Also it doesn't mean the user
has to change the URL they visit and everything for them will just
work! The developers know the difference.

Good approach!

Re: Clearing Browser cache for upadated deployments

[mat]

Hi,

What I usually do is append a random querystring (for each new
version) to the javascript include on the HTML page.

e.g

http://www.google.com/MyScript.js?
version=20081101">

The browser sees this as a different URL to "http://www.google.com/
MyScript.js".

Re: Clearing Browser cache for upadated deployments

[[EMAIL PROTECTED]]

I have similar problem to what Eggsy has described, whereby in order
to view the  most recent changes it becomes necessary to clear the
browser cache. Unfortunately, apart from a couple of minor JSP pages,
most of our system is built entirely using GWT.

Is there some approach within the GWT code, where you can detect a
version or timestamp which can be used a reference for how upto date a
web app is? I mean I'm looking at perhaps doing this with periodic RPC
calls to the server to check if the web app is upto date and in the
case it is not forcing the browser to refresh (is this even
possible??).  I dont like this rather crude approach and would prefer
something which can be left to the app server or apache.

Hi imran,

We have experienced the same problems as you describe in which the
user has to shift reload their browser!

As our app is a J2EE app with JSP's we aim to try and solve this with
the JSP no Cache directives?

This is how it *should* work, out of the box.  Do you have a specific
counterexample?

Clearing Browser cache for upadated deployments

[[EMAIL PROTECTED]]

Hi,

Basically I would like to know how to support the case where we would
like to deploy an updated application and want changes to be reflected
on the browsers without the user needing to manually clear their
cache. If there isnt a gwt solution, is there an apache or tomcat
solution for handling this?

Thanks,

Imran
