Strange type of POST

[Manuel]

I have to log into a website and retrieve some information. The problem is
that the post isn't "normal". I'm used to passing post values in the form
of: Variable1=Value1&Variable2=Value2 etc.

I used Live Http Headers to retrieve the POST information, I included it at
the end of this message.
Can anyone tell me how to make THIS kind of post?

Another thing,
"Content-Type: multipart/form-data;
boundary=---------------------------277301736415408"
This is the first time I see "boundary" as part of the post. What does this
mean?

Thx, here is a copy of the http post, I just replaced the UserName and
Password with bogus ones and the website address with "<Address Removed>"

btw, in Internet Explorer ieHTTPHeaders reports the same post information. I
say this this because at first I thought it was Mozilla the one who
"screwed" up the format

its a standard multipart/form-data form POST. this format is usually used
when there is a <input type=file> control on the page. the post data looks
like any generic multipart mime attachment email message.

a boundary is defined in the header and is is used to delimit the mime-type
data. the mime data starts with a standard mime content header.

note: form-data is the form post data. the mime headers, data and boundary
are delmited by <lf>'s. there is an additional <lf> after the headers before
the data starts. files or attachments are usually base64 encoded (i forget
the mime-header, but you can look it up).
