Doesn't forward all get parameters in request

[kbfirebreather]

I'm trying to proxy a request like this:

https://cors-container.herokuapp.com/https://www.finewineandgoodspirits.com/webapp/wcs/stores/servlet/SearchResultsView?storeId=10051&catalogId=10051&langId=-1&sType=SimpleSearch&resultCatEntryType=2&showResultsPage=true&searchSource=QbeginIndex=0&pageSize=15&sortBy=5&searchTerm=oban&SearchKeyWord=oban#facet:&productBeginIndex:&orderBy:&pageView:&minPrice:&maxPrice:&pageSize:&

But the request that gets sent ends up being:

https://www.finewineandgoodspirits.com/webapp/wcs/stores/servlet/SearchResultsView?storeId=10051

Is there something special I need to do for it to pass along every GET parameter?
