 Posted: Thu Jun 10, 2004 9:33 pm Post subject: Show HTML Re-directs |
|
|
Hi all,
Here's a filter that lets you know when your being redirected to another site. I wrote this because I got tired of being redirected, especially while doing searches, to sites that I would otherwise not visit. This filter allows me to view a link to the location that I'm being redirected to so I can choose if I want to go there or not.
The filter works by checking the "Location" & "Content-Type" headers when a 302 response (actually 30*) is received. If the Location is not related to the Host & the Content-Type is html, the "Location" header is changed to point to a html file that I added to proxo's html directory. This html file uses javascript to write a link to the web site that you were being redirected to. Click the link & your on your way, otherwise, use the browsers back button.
Here's the header filter:
| Code: |
In = TRUE
Out = FALSE
Key = "Location: Show HTML Redirects (in)"
Match = "\1$IHDR(Content-Type: text/html)$RESP(30*)&\w://(^\h)"
Replace = "http://local.ptron/redir.html?dest=\1"
|
Here's the HTML (save as redir.html & put in proxo's html folder:
| Code: |
<html>
<head>
<title>Page Re-Direction!</title>
</head>
<body>
<h1>You are being re-directed to the following site:</h1>
<script type="text/javascript" >
var d, i;
d = String(window.location);
i = d.search(/[=]/)+1;
d = d.substr(i);
document.write('<a href="'+d+'" >'+d+'</a>');
</script>
</body>
</html>
|
This was tested using firefox & google.
I have noticed that many redirects are missing the Content-Type header, or have the wrong mime-type. In my config, I added header filters to "fix" this, you may find that you'll have to do the same.
Comments welcome,
Mike
Edit: removed space from redir.html script tag, doh

| It's blocking redirects - but it's not showing anything at all after the "following site:"... It's blank... |

Hi ProxFox,
Ok, I just tried this with IE, redir.html opened in a new window, but the link was missing. Must be some code IE doesn't like. I'll see if I can modify the script to work with both of them.
Mike
Fixed, I edited the original post. Thanks for reporting it! |
