apache technical question anyone!?
 

Sorry a bit off topic but im in a pinch to find this.

How do you pass the broken link in a 404 to a script? Here is an example:

ErrorDocument 404 404/404.pl?brokenlink=$LinkITried

Use REQUEST_URI

I use and then when index.php is requested by Apache the environment will be as if the file which was not found existed. Take a look at for example the $_SERVER (PHP example) array when you request a 404 file.

I've seen it behave otherwise on other servers though, where the user plainly gets redirected to the 404 page instead. I assume it's some Apache directive for how to show error documents.

This doesnt do anything 'cept pass the acho command.. Im needing this for .htaccess.. I tried using php as the 404 and invoking request_uri but all i get is the current script name or the html it came from. Not the link that was 404 to begin with.

php is only showing the php as the link I requested on my server. Not the link I really wanted.

Setup a normal 404 page, then request the script in your 404 page with an image tag using the REQUEST_URI

Say what? Oh I just found out I cant use php anyway it has to be perl.


there isnt just a fucking variable in apache to pass this? Geez why does this have to be so difficult? ;)

You have to edit your httpd.conf and and uncomment or add the ErrorDocument 404 directive. This can be set global or in your virtual section.

ErrorDocument 404 /404.html works as well as a external redirect with a complete URL. (note that in this example 404.html would have to be present in your document root dir.)

There should be some example lines in your httpd.conf

If you don't have access to your conf files you can also use .htaccess to forward the404 errors

try adding a slash in front of the first directory.

I just realized you're trying to pass a variable to it.

The referer will be picked up by the script automatically. If you're using perl as cgi, look into the CGI.pm docs to see how its passed.

If its mod-perl, checkout the Apache::Registry docs

I think the refering url is also an @ENV variable.

$ENV{'HTTP_REFERER'};

Replace the haha shit up top with a shift+[

2 things you have to keep in mind.

1. Make sure everything is relative. /404/404.pl is a good start.
2. IE will *NOT* show your custom 404 page if your 404 page is less than 10k. You can just fill the damn page with dots. That'll work.

I dont want the referer I want the link you click on that is dead so i can work with it in perl. I have the referer already. ;)

The script runs fine just no way to display the link that was dead in the first place.

in the environment variables, look at REDIRECT_ERROR_NOTES or REQUEST_URI, thats the page that called the 404 (the page that doesnt exist)

No matter what I do I just get the page the person was last on or the page they are currently on I cant seem to get the page they wanted to be on that was 404.

does the 404 redirection work??

I tested this on one of my servers and it works fine. Double check your perl / apache settings.
