Base64 URLs

[Leppy]

Hello,

 

I use the following code to encode my URLs on my site:

 

urlencode(base64_encode("blah blah blah"));

 

Which results in someting like this:

 

YmxhaCBibGFoIGJsYWg

 

And then I put a link on my site using this code

 

<a href="/script/YmxhaCBibGFoIGJsYWg/">Click me</a>

 

It works fine. Although to make a long story short, I added, inside the script who handles the URL, a debug function to let me know if the code "YmxhaCBibGFoIGJsYWg" exist in the DB or not. If it doesn't it sends me an e-mail with the user's browser and requested URL.

 

I've been getting emails lately and I'm clueless about what might be the problem. It is mostly the following User Agent:

 

Java/1.6.0

 

and sometimes:

 

Microsoft URL Control - 6.00.8862

 

The requested URL by both browsers is:

 

/script/ymxhacbibgfoigjsywg/

 

 

It looks like they are not taking the capital letters in the URL. It is a bug in the browser or it is a bug in my script/URL ?

 

If it is a bug in the browser, is there a way I could use only non-capitalized letters with base64 or an alternative of base64?

 

Any would be appreciated!

 

Thank you,

urlencode(strtolower(base64_encode("blah blah blah")));

or do an insensitive comparison?

[Leppy]

That might work, although I'm not sure how I will be able to decode the string to find "blah blah blah" if the base64 is strtolower.

 

Any idea?

or do an insensitive comparison?

 

How do I do that? Could you link me to a php reference, I could read more about it.

He's just saying to check the base64 url against the db with strtolower on both.
