CDN getfile.php not working properly

zork · 11-05-11, 03:48 AM

I'm having an error with the download of the latest Roth UI.

http://www.wowinterface.com/download...hUIDiablo.html

The download link is:
http://www.wowinterface.com/download...5-RothUIDiablo

Which translates into:

Code:

http://cdn.wowinterface.com/downloads/getfile.php?id=9175&amp;d=1320427624

The problem is this

Ampersands (&'s) in URLs

Another common error occurs when including a URL which contains an ampersand ("&"):

 <a href="foo.cgi?chapter=1&section=2&copy=3&lang=en">...</a>

This example generates an error for "unknown entity section" because the "&" is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert &copy=3 to ©=3, which may cause the link to fail. Since &lang; is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to 〈=en. And one old browser even finds the entity §, converting &section=2 to §ion=2.

To avoid problems with both validators and browsers, always use & in place of & when writing URLs in HTML:

<a href="foo.cgi?chapter=1&section=2&copy=3&lang=en">...</a>

Note that replacing & with & is only done when writing the URL in HTML, where "&" is a special character (along with "<" and ">"). When writing the same URL in a plain text email message or in the location bar of your browser, you would use "&" and not "&". With HTML, the browser translates "&" to "&" so the Web server would only see "&" and not "&" in the query string of the request.

There is an amersand html string in the url which bugs out the server.

Browsers itself replaces & amp ; in HTML to & but not the server. It needs a clean URL without any HTML substitutions.

If I correct the URL by myself it is working

Code:

http://cdn.wowinterface.com/downloads/getfile.php?id=9175&d=1320427624

What browser? Firefox handles it when I try to download...

*Edit*

As for errors in html syntax, don't start... there are nearly 200 errors and 100 warnings in the html on the page for download, lol. :P

Interesting. My Firefox (7.0.1) bugs out on the download.

*edit*
I had an idea and it worked. I cleared my Cache and now it is working. But what the heck would place anything in my Cache (other than a static html page) that would do this.

If I click the link again after I clicked it once the error appears again. Lol.
Maybe there is more than one server for downloads and some having a bad file? I can only guess.

Very odd, but considering how each Firefox runs various addons others dont, maybe somehow an addon did something. :P

But, still you have a point; & is only to be used in the "href" attribute of a <a> tag, it will be automatically translated into "&" by the browser when used, but shouldn't remain as "&" or the browser has messed up.

Also a common problem is doing this sometimes "&amp;" (double & escaping) may also cause problems, hehe. Not applicable to this situation tough.

Thanks for the heads up. I've switched out the forwarding to our CDN to use a plain & for the date line. Let me know if that has fixed it for you.

I tested this with nearly every browser out there along with curl -O and wget and never had a problem. I wonder what you have that is causing this? What AddOns for FireFox are you running?

BTW moved this thread... if you post in this forum I get an email alert and see things quicker.

I had this same problem running Chrome. Clearing the cache as stated above fixed the issue.
