Wireshark TCP and HTTP question.

Hello all.
This is my first post and thank you for your forum.

Here is my question.

I have a simple setup at home and I was capturing some data with wireshark.
Data between a workstation and the web server, requesting a page.
Simple enough.

Now when I open wireshark, I apply the TCP only filter for both capture live data and for display data but on the display window I am also getting HTTP along with TCP.
I just need to view TCP, so I can understand sequencing, headers and so forth.
HTTP is at the application layer, why am I seeing it here? I am confused.
Help?

Here is a screenshot.

Cal::DAV(3pm)						User Contributed Perl Documentation					     Cal::DAV(3pm)

NAME
Cal::DAV - a CalDAV client SYNOPSIS
my $cal = Cal::DAV->new( user => $user, pass => $pass, url => $url); # the ics data will be fetched automatically if it's there # ... or you can parse some ics $cal->parse(filename => $data); # cal now has all the methods of Data::ICal # you can now monkey around with the object # saves the updated calendar $cal->save; # deletes the calendar $cal->delete; # lock the file on the server $cal->lock; # unlock the file on the server $cal->unlock # steal the lock $cal->steal_lock; # also $cal->forcefully_unlock_all # and $cal->lockdiscovery # resyncs it with the server $cal->get; # Get the underlying HTTP::DAV object my $dav = $cal->dav; DESCRIPTION
"Cal::DAV" is actually a very thin wrapper round "HTTP::DAV" and "Data::ICal" but it may gain more functionality later and, in the mean time, serves as something that TESTING
In order to test you need to define three environment variables: "CAL_DAV_USER", "CAL_DAV_PASS" and "CAL_DAV_URL_BASE" which points to a DAV collection that the user supplied has write permissions for. It should be noted that, at the moment, I'm having problems finding a CalDAV server that allows me to create files and so I can't run all the tests. METHODS
new <arg[s]> Must have at least "user", "pass" and "url" args where "url" is the url of a remote, DAV accessible ".ics" file. Can optionally take an "auto_commit" option. See "auto_commit()" method below. parse <arg[s]> Make a new calendar object using same arguments as "Data::ICal"'s "new()" or "parse()" methods. Does not auto save for you. Returns 1 on success and 0 on failure. save [url] Save the calendar back to the server (or optionally to another path). Returns 1 on success and 0 on failure. delete [url] Delete the file on the server or optionally another url. Returns 1 on success and 0 on failure. get [url] Refetch the file from the sever to sync it - Alternatively fetch an alternative url. These will lose any local changes. lock Same options as "HTTP::DAV"'s "unlock". unlock Same options as "HTTP::DAV"'s "unlock". steal_lock Same options as "HTTP::DAV"'s "steal_lock". lockdiscovery Same options as "HTTP::DAV::Response"'s "lockdiscovery". forcefully_unlock_all Same options as "HTTP::DAV::Response"'s "forcefully_unlock_all". dav [HTTP::DAV] Get the underlying "HTTP::DAV" object or, alterntively, replace it with a a new one. cal Get the underlying cal object auto_commit [boolean] Whether to auto save on desctruction or not. Defaults to 0. message Same as "HTTP::DAV"'s "message" function. errors Same as "HTTP::DAV"'s "errors" function. AUTHOR
