[RESOLVED] How to Retrieve Invalid URL ??

[chan0923]

Dear all, I need some help on this:

Basically what i want to do is, whenever a visitor enters an invalid URL, I would like to redirect to a php file, and then I would like to retrieve the invalid URL and do some string manipulation with it.

Let's say visitor type www.mydomain.com/blahblahblah , which is an invalid url. In stead of the standard "404 not found" page, i want all 404 request to be redirected to a php file, and get the whole "www.mydomain.com/blahblahblah" string for some processing.

So far I've managed to make the redirection thing works by adding

ErrorDocument 404 /somefile.php

in my apache configuration file. However, I can't get the invalid URL. I try to get it from getenv("HTTP_REFERER"); but it's empty.

Any ideas on how to achieve this? Thanks a lot !

In your somefile.php error script use the REDIRECT_URL variable to get the bad file that was requested.

Like this:

//in the error php script that handles 404 errors

echo $_SERVER['REDIRECT_URL']; 

You can also use the REQUEST_URI server variable.

That will output the bad file on the error page. Note it does not include the domain name, so for example it would return "/blahblahblah"

OK, I've fix the problem!

At first I used:
ErrorDocument 404 http://localhost/..../myphp.php

Which the Apache server acts to REDIRECT to the page, not include it for processing. Thus, echo $_SERVER['REQUEST_URI'] and $_SERVER['REDIRECT_URL'] are both empty.

Once I change it to:
ErrorDocument 404 /mydomain/myphp.php

then everything works perfectly.

Thanks for the help!!
