OpenKeyval.org is a completely open key-value data store, exposed as a drop-dead simple web service. The goal is to make this a very easy way to persist data in web applications.
Fixed with 429cf89a2694a1d2641a4f76365a22cc0ab216dc - it looks like the original behavior was by design, but I changed it anyway. For review by shinyplasticbag#5
When you create a key with any number of spaces as the value, the key is deleted.
For example, space=%20& , gets deleted. However, space=%20a%20 , works as expected.
