Location (full url) of current page?

[Anon]

Hello!

I am trying to write a script that will allow users of my hosting server to set up their own subdomains. The script has to compare HTTP_HOST with an array of subdomains and then redirect to a directory. But when I request HTTP_HOST, headers have been sent so I cannot perform Header("Location: ..."). After trying and trying for example JavaScripts' location.href I came up with a solution that uses two files: one with a <META HTTP-EQUIV="Refresh"> to another script while appending ?host=$HTTP_HOST. The other script can then compare $host in stead of $HTTP_HOST. This works ok.

But somehow this looks silly to me since php can then get a hold of the GET variables which are in the url, but why can't it get the entire url that's in the location-bar of my browser without having to request HTTP_HOST?
In other words, is there any other way to write a script as desribed above?

Thanks very much in advance!
I apoligize for my (maybe) bad english

Never mind! I made a stupid mistake! It wasn't the HTTP_HOST request that made it impossible to header("location: ...") but some stupid echo remark I put in my script to check things were working...

Sorry!

1. Re-write your page so that you may actually use the header() function.

2. Stay away from META HTTP-EQUIV tags if possible. The META HTTP-EQUIV tag has numerous drawbacks, and should only be used when a better solution is not possible (e.g. for people who aren't fortunate enough to have PHP access). It's much better to use real HTTP-headers (using PHP's header()-function).
   Note that META NAME is fine.

3. Be careful about the HTTP_HOST variable. It's set by the browser-user. Sometimes, it's better to use the SERVER_NAME variable.
