When my code hits my javascript file, it uses an old version (before I made recent changes). The page in debugger is titled: WebResource.axd?d=...[dynamic][read only].

It is not the current .js file I have saved with my application.

How do I fx this?

Check this : http://stackoverflow.com/questions/206783/when-does-browser-automatically-clear-javascript-cache

You need to add a virtual random and useless parameter at the end of the source name.

add a dummy query string with a dummy value to the URL of the JS file.

Here is a little trick I like to use if I make a big change to a javascript file that I know will cause problems for people who have it cached:

Whenever I include a script in a page, I use the following format:

<script type="text/javascript" src="myscript.js?ver=1"></script>

Now, when the user views this page, they cache 'myscript.js?ver=1'. Whenever I want to force the user to reload a new and improved javascript file, I change the url to 'myscript.js?ver=2'. The browser doesn't use the cache, because it can't find the file, and it caches 'myscript.js?ver=2' for the next time they visit the page.

In the OnPreRender event of my class I had the following code:

string scriptLocation =
                    Page.ClientScript.GetWebResourceUrl(this.GetType(), "querySections.querysection.js");

I changed querysection.js to querysection2.js . That didn't work.

I tried, querysection2.js?ver=123. That didn't work.

I hard coded into my .aspx page:
<script type="text/javascript" src="/queryAbstracts/querySection.js?ver=1"></script>

That didn't work either.
The browser is still reverting to the old version.

I think I might have figured out what the problem is. My main project's bin directory has references to the projects, one of which contains the javascript file. I'm guessing that the DLL referenced in the BIN directory contains the old javascript file. Is that possible?
I may just need to update the DLL references in the BIN directory. I'll play around with that and see how that works.

I was copying the DLL out of the project and copying it to the BIN folder of the main project. Rebuilding the page, I guess, was building the DLL in the original project and not the one copied to the BIN folder.

The above answers did not pertain to my situation, but they did increase my knowledge so I feel that they deserve some points.
