There was a problem on my webpage using Web Proxy on RB750G with RouterOS 4.11 - the CSS file (generated by PHP) was not loaded in Opera browser (I’ve tried 10.61 and 10.00). I’ve spent few hours to discover the reason, here is essential demo:
- this file is not working: http://www.zervan.info/tmp/short.php
- this file is working: http://www.zervan.info/tmp/short2.php
First file is still loading, time is running without any result - proxy is holding connection and waiting for.. I don’t know what:
Here is simple source of this file:
<?php
echo ".";
?>
The second file is working fine, because HTTP header Content-Length is set:
<?php
header("Content-Length: 1");
echo ".";
?>
The problem is that PHP files usually don’t set this header (it is not so simple). Problem is appearing only when file is very short - less than 4 KiB if gzip compression is disabled (it is more complicated when the compression is enabled) - that’s why almost every web page is working fine.
I don’t know if it is a bug in RouterOS or Opera or webhosting server:
- everything is fine in Opera when I use no proxy or Squid proxy;
- everything is fine with Mikrotik proxy when I use Firefox;
- everything is fine when I put these files on my local web server.
Does somebody know?
