290676 - directory index is called (silently) after request of other page

Status: VERIFIED INVALID

(Core :: Networking: HTTP, defect)

Description

[mozilla]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.7.6) Gecko/20050226 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.7.6) Gecko/20050226 Firefox/1.0.1

When I open the page http://anyurl.any/anything.php firefox always calls
http://anyurl.any/ or http://anyurl.any/index.php (i dont know which one but i
think it is http://anyurl.any/ = directory index) after ~200 miliseconds. The
Page is requested by the browser (which can be easily proofed by php code which
is executed) but will not appear! Why does firefox request the directory index?

Reproducible: Always

Steps to Reproduce:
1. call http://firefox.suavemente.de/bug.php
2. Refresh after few seconds
3. Look the table

Actual Results:  
You can see that ~200 miliseconds after /bug.php was called (and insertet actual
time into database) /index.php was called (and also insertet something into
database to proof that it was called)

Expected Results:  
Of couse /index.php shoud not be rtequestet. Only /bug.php

Source of my php example (both bug.php and index.php):

<?php

	$db = mysql_connect("localhost", "webXXX","XXXXXXXX");
  mysql_select_db("usr_webXXX_1",$db);

	$sql = "INSERT INTO `firefox` (`from`,`microtime`) VALUES ('"
.$_SERVER['PHP_SELF'] ."','" .microtime() ."')";
	echo "<br /><br /><br /><b>SQL:</b> <code>$sql</code><br /><br /><br /><br />";
	mysql_query($sql);
	
	echo "<table><tr><th>id</th><th>page</th><th>microtime</th></tr>";
	$result = mysql_query("SELECT * FROM `firefox` WHERE 1 ORDER BY `id` DESC");
	while ($myrow = mysql_fetch_array($result))
	{
	  echo "<tr><td>" .$myrow['id'] ."</td><td>" .$myrow['from'] ."</td><td>"
.$myrow['microtime'] ."</td></tr>";
	}
	echo "</table>";
	  

?>

hmm, but I can reproduce this with FF1.0.3 and a nightly FF trunk build.
-> networking to find out where this index.php comes from

Maybe it has something to do with bug 247913 ???

Comment 4

[Boris Zbarsky [:bzbarsky]]

So... I can't reproduce this in a debug Firefox build on that page.  But I think
that's because the part of the page below the SQL insert statement just never
gets changed (the new insert seems to be ignored)?

Is there a reasonable testcase actually showing the bug?

Note that an HTTP log shows Firefox on Linux just requesting /bug.php and
/favicon.ico

Comment 5

[Matthias Versen [:Matti]]

The testcase seems to be broken (doesn't add new entrys)
Reporter: Can you fix that ?

You can see the loading from index.php around #50 on that bug and that's from me.

Comment 6

Fixed! Now i put a link to empty the table when it is "full" (128 entries)

Comment 7

[Boris Zbarsky [:bzbarsky]]

OK.  So I _do_ see the bug (in that the index.php appears in the table), but
Firefox is NOT making that request (verified via HTTP logging).

Does you server call index.php for the /favicon.ico request or something?

Comment 8

[Boris Zbarsky [:bzbarsky]]

Ah, yes.  Loading http://firefox.suavemente.de/favicon.ico directly adds
index.php to the table over and over again.  So it's just a server bug.

But I did not have that bug using IE

Comment 10

[Matthias Versen [:Matti]]

true but IE doesn't ask for the favicon unless you bookmark the page.

verified invalid (I suck: i should have catched that favicon loading)
