[jQuery] What causes a query string when requesting jQuery? e.g. /jquery-1.3.2.min.js?_=12553…
I'm troubleshooting a page display glitch involving jQuery & AJAX.
When the glitch happens, Fiddler shows the following as one of the
requests:
GET /Scripts/jquery-1.3.2.min.js?_=1255309685187
Normally, the request has no query string and the response status code
is 304:
GET /Scripts/jquery-1.3.2.min.js
However, every so often a query string is appended. Where does this
query string come from? What does it mean?
I wonder if the AJAX call fails, and then jQuery is refetched with
that query string for some reason.
The webserver is Visual Studio's Development Server, and I usually see
this in IE8. Occasionally I'll see it in Firefox though. The app is
ASP.NET MVC.
