i analyzed a page that i’m working on with live http headers addon for FF and im seeing that is making request to the same page 2-3 time during the load of it. i checked for empty img tags that could be the reason but there is none on the html code. is there any addon out there or something that could let me track what resource is firing this request? or any other recommendation of what is should look apart from the empty img tags.
the page have several javascript libraries and mootools with ajax calls, but none of them is causing it as they load the resources and the ajax calls are get request passing several parameters to the page, this unexpected request are clean one, whiteout parameters.

Shadow.
SOLUTION
monitoring from the server side the request and commenting code, i realized that was making 3 request’s
1) from a popup blocker checker that open an about:blank in theory but it was requesting the same page
2) a class used to check if flash was enabled
3) the yslow plugin for FF was making the last one.
i’m worried about this last one as it screw up a feature in my app, so i will need to have some alternative thing here 🙂
if you have access to server logs, you can find the answers there.
finally, you can use some sniffer software to see all http request sending by browser
