I tried to open a website that is hosted on Port 80.I captured all the packets related to that particular Site.Here,I am seeing a mismatch between no.of GET Requests initiated(Showing 95) vs Object list in File>Export Objects >HTTP(Showing 28) Is this a real discrepancy? I am under the impression that each GET Request is an object and hence both should be same.

I am under the impression that each GET Request is an object

Not necessarily:

We couldn't find the file you requested. If you're lost, you might try:
<ul style="list-style-type: none">
  <li><a href="/">The main page</a></li>
  <li><a href="/download.html">The download page</a></li>
  <li><a href="/docs/">The documentation</a></li>
<div class="clear"></div>
<!-- Shamelessly stolen from -->
<img src="/image/im-in-ur-servr-sniffin-ur-paketz.jpg" style="margin-left: auto; margin-right: auto" alt="">

That's a GET request, but it returned an error; I guess you could argue that the error page is an object, but it's normally not an object that somebody intended to get.

Did any of the GET requests get a reply code other than 200? For example, did they get errors (4xx or 5xx), or a 304 "Not modified", or a 302 "Moved temporarily", or a 301 "Moved permanently", or...?

Yes all those missed in Objects got response code 304 Not Modified. Thanks for letting me know the undercurrent behavior.Clearing the browser cache and repeating the test worked.
