A pleasant surprise from Slashdot
I'm working on a project for a client, and I need to see exactly what
transpires between a web browser and a web server, since what I've written
isn't exactly working correctly.
So towards that end, I've written a program that acts as a very simple web
proxy server—all it does is pass the data on to a real web proxy server, but
it also dumps everything to disk so I can examine the traffic (it's not
enough to look at the pages, I need to see what else is going on in HTTP
(HyperText Transport Protocol)).
As a test, I went to Slashdot [1]. As expected, the program saved all the
sessions, didn't crash and didn't leave any zombie processes [2]. And then
going through the saved files when I found out that there's an Easter Egg [3]
in the pages Slashdot [4] send out.
You normally can't see this, even if you view the source of the page, since
the Easter Eggs aren't part of the page. They're in the header portion of the
transfer (not to be confused with the <HEAD> section of an HTML (HyperText
Markup Language) page—there is a difference). For instance, on the HTML pages
(and it's only sent with pages that are text) on one page I found:
> HTTP/1.1 200 OK

> **Server:** Apache/1.3.26 (Unix) mod_perl/1.25 mod_gzip/1.3.19.1a

> **Pragma:** no-cache
> **Connection:** close
> **Content-Type:** text/html
> **Content-Encoding:** gzip
> **Content-Length:** 10760

And on another one I found:
> HTTP/1.1 200 OK
> **Date:** Sun, 30 Jun 2002 02:11:36 GMT
> **Server:** Apache/1.3.26 (Unix) mod_perl/1.25 mod_gzip/1.3.19.1a

And yet another one:
> HTTP/1.1 200 OK
> **Date:** Sat, 13 Jul 2002 10:09:23 GMT
> **Server:** Apache/1.3.26 (Unix) mod_perl/1.25 mod_gzip/1.3.19.1a

It seems to be quotes from Futurama [5], but I can't be entirely sure, as
I've never seen Futurama. But still, it's neat finding stuff like this buried
in programs (or websites as the case may be).
