how does i need to be able to use my web client to login with a username and password..
in other words i want to be able to perform this line in an http request:
:
document.implogin.submit();
i think i need to use the http post command, but in what syntax.. i dont really know html/scripting.. and dont plan on learning for this short term project since im just doing this for fun..
so should i look into http post requests more?
how can i know the systax of my http request by looking at the source code of the webpage, specifically the "submit" button..
thanks a bunch all..

To get a reference to the form implogin, you don't use document.implogin, but document.getElementById("implogin"). You can store the result of that in a variable if you wish.

Oh, and this should be in the JavaScript forum.

If you want to check the form, before submitting the form. In the <form> tag put onSubmit="submit_login();" . If submit_login() returns false, the form will not submit.

thanks for the replies guys...
i will make my question a little more specific:
This is what i sent to the IP of the website:
:
GET / HTTP/1.1\r\n
Accept-Encoding: gzip, deflate\r\n
Host: 192.168.141.107\r\n
Connection: Keep Alive\r\n\r\n
what should i send next to get the source code of the page after i login?
how can i access
:
document.getElementById("implogin")
throughhttp requests?

alright i did it... but in a very peculiar way. i made another program which emulates the server of the website that my client program was trying to access it..
this server listens for a connection, it recieves an http get request from the internet browser.. then it send the code i posted below (html/javascript)..
then the server closes the connection.. i filled in the username and password in the Internet browser and clicked submit.. whose request offcource went to my emulation of the webserver im trying to see.. i studied the http request, i didnt find any relation to the page's source code.. this is what happens when you press the submit button:
:
POST /imp/redirect.php?Horde=4db15905f8d71e1d00e5f2f376adc085 HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-
excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwav
e-flash, */*
Referer: http://192.168.141.107/
Accept-Language: en-us
Content-Type: application/x-www-form-urlencoded
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322
; .NET CLR 2.0.50727)
Host: 192.168.141.107
Content-Length: 193
Connection: Keep-Alive
Cache-Control: no-cache

actionID=105&url=&mailbox=INBOX&imapuser=hbe02&pass=mypassword&server=pop.aub.edu.lb&p
ort=143&namespace=&maildomain=aub.edu.lb&protocol=imap%2Fnotls&realm=&folders=IN
BOX.&new_lang=en_US&button=Log+in

you can notice where the user and pass went.. user:hbe02 , pass: mypassword

after i found out that the internet browser sends this request when i submit the form.. i used this request to access the webserver back in my original web client program..
any critique to my method?
