Altho' I can (just about) cope with Apache Rewrite stuff, I'm getting confused translating to the Abyss Way. I hope someone here can help.

I want to do this

Code:
if REQUEST_URI ~ ".*zeltus.eu/secret.*"
then
force redirect to "http://zeltus.eu/public/index.html"
fi


But, despite the help docs, I'm unsure what the Virtual Path Regular Expression box is for, nor the difference between "Perform an internal redirection" and "Perform an external redirection"

The rule itself seems to be simple...
Code:
REQUEST_URI Matches with .*zeltus.eu/secret.*


but I've put it here in case I'm misunderstandfing that as well!

As ever, any help gratefully received.

Cheers

Bill

Hi Bill.

If you're trying to match any URI that begins with /secret

the virtual path regular expression would be:
Code:
/secret(.*)

Case-sensitive: I would uncheck this
If rule matches: Perform an external redirection
Redirect to: http://zeltus.eu/public/index.html
Append query string: doesn't matter (just leave checked)
Escape redirection location: doesn't matter (just leave checked)
Status code: 301 - Moved Permanently

This rule would redirect the following URIs
/secret.txt
/secret.html
/secret/
/secret/anything.php
/secret

Does that give you what you're looking for?

BTW, as for what domains this regex works with will depend on what domains are setup for this host in Abyss. So, of course, I'm assuming the host is already set up to work with zeltus.eu.

Thanks for the help... most of it is clear now except

a) shurelee REQUEST_URI is populated witha full URI string i.e. "http://zeltus.eu/secret.html" or similar? Or does Abyss work differently? (is there a way to log or otherwise, "see" what Abyss is seeing, for diagnostics

b) what is the Virtual Path Regular Expression used to compare against? i.e. what is the string that Abyss receives that it then can use this RE to check against?

Other than that, it's all going swimmingly well. Much thanks.

Bill

Incorrect. The zeltus.eu is found in the HTTP_HOST variable, not REQUEST_URI. You can see all the variables Abyss sees by turning on logging. Click 'edit' for advanced parameters on the URL rewriting page. Turn on 'Log variables'. Note: this file will get big very quickly! Turn it off as soon as you can.

You can get more familiar with those variables if you have PHP installed. Make a simple PHP file that looks like this:
Code:
<?php
foreach($_SERVER as $var => $string) {
echo "{$var} = {$string}";
}
?>

The virtual path regex is compared against the REQUEST_URI. If it matches, the rewrite rule is acted upon.
