HTTP Header Question

Hello EE,

Is it possible to read the value of a POST Header Entity Response Body value ?
in other words, If I have an Entity  Content-Length : 56

how can I know its value ? I know its the length, but how can I see what is it? doesnt matter if its ASCII or something else to me

another question attached to this is, if I know its value, is it possible to achieve the same results with a Querystring after ?

The simple answer is:

The .Net version of $_GET[] is :

 Request.Querystring["parameter1"]

The .Net version of $_POST[] is :

 Request.Form["paramName"];

Frameworks that are available with .NET hide these under other functions.

Can you explain more about the problem you are trying to solve?

YEs alright Kaufmed :

in Fiddler4 software, I see that whenever I type something in a Textbox, I see a Link (no querystring) doing a POST with a response body of the name "textValue"  and value : whatever I typed..

I want to be more efficiant for the job I have to do and I would like to "post" stuff without me going to type every hour myself.
I want my vb.net to do the same thing. So I was trying to understand what to do as a POST to achieve the same thing as If I was typing on the keyboard on that textbox
Your help has saved me hundreds of hours of internet surfing.

In the web, HTML forms are used to 'POST' data to a server.  The only common method for 'POST'ing is to use cURL.  PHP has it's own built-in cURL extension, I don't know if .NET has such a thing.  More info here: https://curl.haxx.se/

Actually, you can use jQuery in an HTML page to post data from a form page.  You might be able to use that to do it programmatically.

If you are simply trying to programmatically post data to a web server, then you would use either the HttpClient our WebClient classes. The former is preferred over the latter.

If I get an error like this :

The remote server returned an error: (403) Forbidden.

on a line :

Dim responseLoginToPage1 As HttpWebResponse = DirectCast(requestLoginToPage1.GetResponse(), HttpWebResponse)

Open in new window


is it possible im just not allowed to do this or maybe its something else I could do wrong ?
