Ajax.net ?? = Press ENTER

Recently, I developed a new version like chatting room, so I used ajax.net.

Then I found a problem.
when I have carriage return and images in the text, the subsequent text will be lost.

Sssssss
Ssssss
Sssssssss

< IMG SRC = "Http: // locahlhost/test.gif" >
Sssss

The result is:

Sssssss
Ssssss
Sssssssss

A lot of things are missing ..
Error. It is related to xx = after the first carriage return.Ssssss = sssssssssssssssssss = Ssssss = sssssssssssssssssssss = Ssssss =

SSS =
SSS =
SSS =
SSS =
SSS =
SSS =

Solution: Use escape and Unescape server. urldecode
