Post subject: IIS chokes on URLs with colons?
Archived from groups: microsoft>public>inetserver>iis (more info?)
I'm programming a script that pulls data out of the PATH_INFO environment variable. All of a sudden, when I try sending some data that includes colons (":") in the URL, IIS chokes and returns a 404 error. Bull****.

Despite the fact that colons are permitted in the path portion of the URL, I tried encoding them and got the same result.

What is the deal with this? Is there any way to make it work right?

For example:
http://www.example.com/script.cfm/blah/

= fine

----------

http://www.example.com/script.cfm/blah::blah/

or

http://www.example.com/script.cfm/blah%3A%3Ablah/

= 404

(both URLs work fine on Apache / Linux).

Hi JMM,

IIS does not permit colons in the URL. This is because the NTFS file system
considers a colon to be a special character that's used to denote alternate
streams within a file. If your example URL below were handled by the static
file handler in IIS, it would attemps to open the stream called "blah"
within a file called "blah" in the "script.cfm" directory under wwwroot.

More specifically, without this limitation, if a client were to request
<a style='text-decoration: underline;' href="http://www.example.com/script.cfm::$data," target="_blank">http://www.example.com/script.cfm::$data,</a> then the contents of the
script.cfm file would get sent to the client instead of invoking ColdFusion
to process script.cfm.

If you want to prevent IIS from parsing your data, then put it either in the
query string or the entity body. A colon would be allowed in either of
those places.

Thank you,
-Wade A. Hilmo,

Well, Wade, thank you sincerely for your explanation, but
WTF?

That is total bullshit. You've got to be fucking kidding
me.

You guys just decided that you weren't going to "allow"
colons in

URLs? You guys really need to take a good long look at
RFC 2396

and get with the program.

Thanks for the suggestions, but if I wanted to put the
data in

the query string, I would have. As it is, I want it in
the path

/ PATH_INFO (something else botched in your servers). And
there

is no entity body in a URL. Colons are allowed exactly
where I

put them, in the path portion of the URL. Again, see RFC
2396.

Jesus christ, thank god I choose Apache.

That type of response is not needed on this newsgroup.

Thank you. I hope this information is helpful.
