What would cause Firefox to request a resource multiple times after a long running script?
I'm noticing some unusual behavior in Firefox when I include an image directly after a call to an external script which is long-running.
For example:
<html>
<body>
<script type="text/javascript" src='external.js'></script>
<img src="/test.gif" BORDER=0 WIDTH=1 HEIGHT=1 >
</body>
</html>
Contents of external.js:
for(i=0; i<999999; i++){ ; }
I notice that when a request to test.gif results in a 404 or 302, Firefox makes another request for that same resource immediately after the script has completed.
127.0.0.1 - - [29/Apr/2011:16:22:22 -0400] "GET /test.gif HTTP/1.1" 404 507 127.0.0.1 - - [29/Apr/2011:16:22:22 -0400] "GET /test.gif HTTP/1.1" 404 507
This behavior doesn't occur for inline javascript, and I have pipelining turned off, so I'm fairly certain it's not related to that. Seems like odd behavior, or I'm just missing something not-so-obvious. Any ideas?
