I'm trying to get a couple WAP pages to work on my Apache 2.0.52 server. They sometimes work, sometimes don't.
For example this wml code works on a cell phone connecting to the site.

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="login" title="login">
<p>
Username: <input name="user" />
Password: <input name="pass" />
</p>
</card>
</wml>

However, the next bit of code (with one additional line of plain text) doesn't work anymore:

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="login" title="login">
<p>
A little more content <br/>
Username: <input name="user" />
Password: <input name="pass" />
</p>
</card>
</wml>

It seems that as soon as the file gets too big, the cell phone gives the error "File format unknown." I downloaded a big wml file from another server that I tested with my cell phone (that worked) but when I put it on my own server, it no longer worked. And yes, I have the AddType lines in my conf file.

One additional comment, when I use an emulator (same model as my actual cellphone) and open a file locally, it always works. But when I try to retrieve it from the server over the internet, it stops working. Again, short files don't have that problem.

I did a little more testing, and some of my WML pages stop working when the size of the page is above 255 B.

Again, this problem only occurs when I load the page over the internet, but not when I load it locally (directly from my HD).

I'm puzzled.
