Webserver parsing chrome input from post request

Question

I am developing a small embedded web server. I want to add parsing of post requests, but I am having a problem with input password fields from Chrome. Firefox and IE work perfectly.

The HTML:

<form action="start.webem" method="post"> 
<input value="START" type="submit" /><!--#webem start --> 

Password: <input type="password" name="yourname"  autocomplete="off" /> 
</form> 

From Firefox I get

POST /stop.webem HTTP/1.1
Host: 127.0.0.1:8080
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100315 Firefox/3.5.9 (.NET CLR 3.5.30729)

Connection: keep-alive

Content-Type: application/x-www-form-urlencoded

yourname=test

However from Chrome, about 90% of the time, the yourname=test is missing

POST /start.webem HTTP/1.1
Host: 127.0.0.1:8080
Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5

Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

Though, occasionally it does work!!!

yourname=test

I cannot find what causes it to work sometimes.

Answer 1

Probably because your HTML is so invalid. Fix that and your problems will disappear...

<form action="start.webem" method="post"> 
<input value="Start" type="submit" />

<p>
  <label for="yourname">Password:</label>
  <input id="yourname" name="yourname" type="password" autocomplete="off" />
</p>
</form>

To your comment:

HTML isn't technically case sensitive, but you should never ever use uppercase for tag/attribute names. That's just bad practice.

I think the reason it sometimes worked is because you had an open paragraph tag, but never closed it, so Chrome was probably sometimes placing the paragraph outside of your form.

Answer 2

It is a chance that you didn't read the second portion of the data from the socket in your web server. That might describe why sometimes it is working.
