POST vars

[altexis]

This is not exactly a PHP question but I hope someone could help

The question is what is the exact format of a POST variable as it travels from one page to another? I mean what is the exact format of the HTTP header containing a POST variable?

I know the corresponding rfc is 2616... but is there any straight forward answer?

thanx in advance 🙂

Hi Altexis,

I'm not near an expert with this, but played around with it a little. this is how it works for me:

when sending the request header, make sure you set the Content-Length (string length of request body*) and Content-Type (application/x-www-form-urlencoded). then after indicating the end of the header with a blank line (\r\n\r\n), you send the name and value pairs separated by ampersand as request body, like "input1=test&input2=testtest".

• make sure the length is exact. if too long, both browser and server may sit waiting for something that isn't going to happen, and if too short, the rest of the request body will be ignored.
