I tried this from bash:
GET http://cetatenie.just.ro HTTP/1.1
It works fine, and I am able to get the page, then I try this from telnet:
telnet cetatenie.just.ro 80 Trying 18.104.22.168... Connected to cetatenie.just.ro. Escape character is '^]'. GET / HTTP/1.1 Host: cetatenie.just.ro
I get an
Internal Server Error (Http Error Code 500)
The thing is, I do not really have access on the Server (it is an app deployed on IIS 7). Why does performing a GET work and accessing it through telnet does not?
All I could think of was that I need to send some additional headers. I tried using the Live Http Headers and sending the same thing that they do :
http://cetatenie.just.ro/ GET http://cetatenie.just.ro/ HTTP/1.1 Host: cetatenie.just.ro User-Agent: Mozilla/5.0 (X11; Linux i686; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Proxy-Connection: keep-alive Cookie: .ASPXANONYMOUS=Ij8RLazqzAEkAAAAMTk5ZjY0MGUtYWU0NC00ZmViLTgyNTgtMWU0MjNlM2IyZWEx0; language=en-US
But it still does not work with telnet.
