Can't understand "Trip to the past"
Can't understand "Trip to the past"
Simply can't figure out what this challenge wants.
I've tried to fake a date in my http request, though I know that a request needs no date.
Also tried to fake the user-agent, no help neither.
Can anyone give me a really really small hint? Thanks.

After some tries, i stopped this level.
I did some workarounds with some injections in user-agent => no luck
tried some extra headers like, date, cache-control and so => no luck
I figured out that user-agent is only cheking for some strings.
i assume something like this pseudo code:
if insideuseragent("MSIE") return "IE"
if insideuseragent("Opera") return "Opera"
if insideuseragent("Konqueror") return "Konqueror"
if insideuseragent("Chrome") return "Chrome"
if insideuseragent("Safari") return "Safari"
if insideuseragent("Gecko") return "Firefox"
... maybe there are more string compares, feel free to complete my list
return "anonymous"
cheers,

Though, I just got it down, with a lot of searches.snibril wrote:You are to young
Which is more confusing is that, at first I used an older version of the specific user-agent string, but it didn't accept it. Next I tried a newer (of course relatively speaking) one, and buff! It worked!
But you're right, snibril, I'm too young to solve this easily.
There is one particular web browser which springs to mind easily to anybody who has witnessed the birth of the WWW, but of course it's not used anymore for a long time by now.gfoot wrote:I tried setting it to the first web browser ever, and it didn't work. I guess that's just too old then.
If you've never heard of it before it's of course impossible to guess out of the blue but certainly possible to research. Some Wikipedia articles about the history of the WWW will guide you into the right direction.
I actually downloaded the source code for that browser to make sure I got the correct user agent string (after some failures). I'm not sure if that is really necessary, it depends on how fascist the checking routine is about the string.
You might even find a working version of the browser in question (depending on your operating system, this might not be easy, however!).

Looking into source code is always encouraged by this group of hackers.

I need a little help,
I also tried to simulate an another browser client and another post date
then I found this Thread and read the paragraph "not the oldest Broser... a newer one works"
and "a search in wikipedia will help"
So I tried some browser versions:
Netscape:
and Mosaic:
But nothing work
really need help
