mstrewe opened a new issue, #1448:
URL: https://github.com/apache/incubator-stormcrawler/issues/1448
The BasicUrlNormalizer will encode links if they are not already URL
encoded.
The Bug occurs when URL has encoded chars in smaller case like
`'/Exhibitions/Detail/NjAxOA%3d%3d'`. (the URL
`'/Exhibitions/Detail/NjAxOA%3D%3D'` is not affected)
In BasicUrlNormalizer.java from line 145-150 the file of the URL gets
unescaped and escaped again. After that the original file and the es-unes-caped
file are compared. It will be
`Exhibitions/Detail/NjAxOA%3d%3d == Exhibitions/Detail/NjAxOA%3D%3D`
(Capital D)
After that the original source URL will be reacreated (line 154) and results
in 'Exhibitions/Detail/NjAxOA%253D%253D'
Can be fixed if the statement in line 148
```
if (!file.equals(file2)) {
```
will changed to
```
if (!file.toLowerCase().equals(file2.toLowerCase())) {
```
UpperCase doesnt matter. But now it does not
