In principle: yes. A web page is served similar to a multipart/mime-message over e-mail. You have some header information (encoded into the URL), some "framework information" and optionally one or several additional data sources (pictures, videos, programs like flash, ...) embedded in this "framework". A browser receives such messages, displays them (quite like a mail reader would do for mails) and - driven by user actions - replies with a similar sort of messages which can range from very simple to equally complicated and similarly structured (quite like you answer a mail with a reply of your own).

Some of the elements i talked about above only work interactively. Both cURL and wget have (limited) provisions to deal with that. That means, some aspects of a user sitting there and interactively clicking/etc. something can be emulated, some cannot.
I hope this helps.

curlopt_verbose
CURLOPT_VERBOSE(3) curl_easy_setopt options CURLOPT_VERBOSE(3)
NAME
CURLOPT_VERBOSE - set verbose mode on/off
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
DESCRIPTION
Set the onoff parameter to 1 to make the library display a lot of verbose information about its operations on this handle. Very useful for
libcurl and/or protocol debugging and understanding. The verbose information will be sent to stderr, or the stream set with CUR-
LOPT_STDERR(3).
You hardly ever want this set in production use, you will almost always want this when you debug/report problems.
To also get all the protocol data sent and received, consider using the CURLOPT_DEBUGFUNCTION(3).
DEFAULT
0, meaning disabled.
PROTOCOLS
All
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* ask libcurl to show us the verbose output */
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
/* Perform the request */
curl_easy_perform(curl);
}
AVAILABILITY
Always
RETURN VALUE
Returns CURLE_OK
