Re: Problem submitting a POST request "by hand"

[Vallo <vallo@xxxxxxxxx>]

The problem is that the URL which I posted to doesn't display in a 
browser again. I want to do the following:
1) www.someserver.com/feedback.phtml sends the user-entered form data to 
www.someserver.com/mailer.php
2) www.someserver.com/mailer.php (the example below) checks these data 
and submits resulting parameter list via POST method back to 
www.someserver.com/feedback.phtml and loads it again
3) www.someserver.com/feedback.phtml displays again in a browser 
according to received POST parameters...
PROBLEM: www.someserver.com/feedback.phtml doesn't load again (a blank 
page is displayed). I discovered by accidant that if I add the echo $c; 
line then the page loades but the &c value's string is seen on the top. 
How can I get the www.someserver.com/feedback.phtml loaded again without 
this trick?
