Apache Alias - removes POST data?

  • 772

I have an alias in my httpd.conf where I'm redirecting a single PHP file to another PHP file located in a different dir.

Though it appears as thought data POST'd to this file doesn't get carried along? Is that the case? If so is there a way to carry it?

I hope this is a nice simple one.

    It depends on what's going on; you mention an alias, and then you mention a redirect, but these are not the same thing.

    The following says, when somebody accesses http://myurl/image, serve up the contents of /www/image. There is no redirect involved here. If a user submits POST data, it will be submitted to whatever path is specified.

    Alias /image /www/image

    On the other hand, Redirect (which, confusingly, also lives in mod_alias) will cause the user's browser to change to another page; using the same example as above:

    Redirect /image http://myurl/www/image

    So when your user accesses http://myurl/image, your server will send back a message saying, "This page has been moved to http://myurl/www/image", and your browser will resubmit the request to the new URL.

    Keep in mind that you can have both an Alias and a Redirect clause on the same path, and the Redirect will take precedence--keep that in mind when looking over your rules. If you really want to see what's going on, open up a terminal and try:

    curl -I http://myurl.com/image

    If you see HTTP/1.1 301 (or 302) or similar, you are being redirected, and the Location field will reveal the new location. Hope this helps!
