Epic #84262: [FEATURE] Update felogin to extbase
EXT:felogin creates urls without cHash
Method getPreserveGetVars unsets cHash.
I don't understand the reason why it has been implemented this way, but this messes the Realurl cache table (now named tx_realurl_urldata) creating duplicated records of an existing record but without the cHash.
correct row as field original_url =
wrong duplicated row as field original_url =
This, as a result, makes Realurl to fail to decode urls and display the wrong product detail page.
