nsafe header "Connection"

[dunix]

Пробвам се да направя една заявка към дб след натискане на бутон.
Като натисна бутона ми дава следната грешка:

Refused to set unsafe header "Connection"

Като зареда php файла директно в браузера ми показва резултатите.

<div onclick="search_not(this);" style="cursor:pointer;height:45px;width:47px; z-index:200" id="menuNotOthers">
	<table cellpadding="0" cellspacing="0" border="0" height="45" width="47" align="left" style="padding-bottom:4px;">
		<tr>
			<td align="center" valign="bottom">
				<img src="images/header_not_black_off.png" border="0" />
			</td>
		</tr>
	</table>
</div>
<div valign="bottom" style="top:0px;position:relative; z-index:200;">
	<div id="not_result" style="position:absolute; display:none; left:0px;"></div>
</div>
