Question

Referer Question: How can I fake it with JavaScript, or PHP, or ASP, etc.

Asked by: jpeterso12345

Basically, I have an online resource through a database vendor that uses the URL referer to authenticate it's users.  I have setup one web page to allow users access to this resource.  

I have been asked to make this resource available through multiple web pages, as designed by our educational web designers.  I don't want to send 5, 10, or 100+ URL's to this vendor, so my question is, can I rewrite the http referer so the vendor will think it came from the URL already setup.

I prefer to have the script create a link that will provide this functionality, but I am willing to look at other options.  

Thanks,

This would be a little difficult to do without using perl, which i am not to skilled at personally,  I couldn't make you a script for this particular resource.

In genral what you are asking though is this

you have web page a on server A
someone asked you to make webpage A available on web page B
B cannot access A because its not on the hosts.allow list (or equiv)
or
A cannot handle the bandwith B would send to it therefore you dont want to allow that to come to pass.

I have 2 ideas,  1 write a perl script that makes a page request that appears to be internal, and display the result in an iframe,  or 2: make a mirror of the site.

Hi jpeterso12345,
why not use a FRAMESET whereas one frame will be the know URL for the vendor.
Every URL that wants to "mirror" this feature will only need to provide that frameset.
Sort of (hope  get it right, haven't used frame for long<g>):
<frameset rows="0,*">
  <frame name="dummy" href="blank.html">
  <frame name="authpage" href="http://full.url.to/authpage.html"
</frameset>

The "authpage" frame will be the one that posts the userdata and will always appear as the correct referrer.

Have fun,
CirTap

I am not sure but if I understood you correctly, you want all referal from all of your pages to go to the vendor, but the vendor should think that they come from one single url. If this is correct you can do this. Have a page say redirect.asp. This page will be the page where all requests go to the vendor. In this page either use querystring or form submission method to pass the target url. For example

http://YourSite.com/Redirect.asp?TargetURL=http://VendorSite.asp?Q1=V1&Q2=V2

In this page have

Response.Redirect Request.QueryString("TargetURL")

All the pages that would have direct link to the vendor's page now should have

<a href="Redirect.asp?TargetURL=http://VendorSite.asp?Q1=V1&Q2=V2">Go to Vendor Site</a>

You will have to work a little to pass all the querystring parameters from original page to the final page but that would not be difficult.

ullfindsmit,

Could you give a little explaination to your reply, I am curious how the bot.htm will accomplish the authentication.

Thanks,

Jeremy
