XMLHTTP post Request - Page Headers?

[sir pannels]

hi all,

When using xmlhttp request for POST as you may know you can have a form target to somefile.php .asp, whatever) and put return false in the onsubmit tag also so the form does not actually submit, yet somefile.php still runs.

That somefile.php just returns a value, the ajax then puts that value in a div..

Problem I have is I do not understand why you need to set content type of somefile.php. Strictly speaking, is it even being called in the browser for display?

The reason I ask is because I set the content type of the file to text/plain and internet explorer just asks me if I want to download or save somefile.php when I submit the form. In opera, it seems to fully submit the form and instead of returning value to the <div> it actually sends me to an entire new page with the value on.

Not really a php question more and ajax/js one so hope i get away with it here.

anyone have any thoughts?
cheers,

When you make a post you should set:
req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

You really just need to set the content type when we are using XML, using responseText really does not care about the type.
