Tomcat triggers ServletRequestListener twice per request...

Hi,

I have a regular HTML page and a ServletRequestListener. For some
reason Tomcat invokes requestInitialized and requestDestroyed twice
for every client request.
In other words:
requestInitialized
requestDestroyed
requestInitialized
requestDestroyed

Could someone explain to me why this is happening? I have NO Filters
or MVC going on here. Just a regular HTML page.

Thanks,

Ahhhhhhhhh! I forgot about the stylesheet! Make perfect sense!

Thanks!

Or the HTML page has a stylesheet link or javascript link or an image tag or
anything else.  As Mark says, use a client tool to trace the requests from
the browser.

At a guess, the browser is making two requests. One for your page and
one for favicon.ico

Use ieHttpheaders (for IE) or Live Http Headers (for Firefox) to
confirm this.

At a guess, the browser is making two requests. One for your page and
one for favicon.ico

Use ieHttpheaders (for IE) or Live Http Headers (for Firefox) to
confirm this.
