URL rewrites - IBM Lotus Domino

[pekka.panula at sofor.fi]

Hi

I have some (wierd) URLs that i need to redirect to a new site. Problem is 
that original site is made with IBM Lotus Domino and URLs are somewhat 
"funny".
My problem is how should i made these redirections to nginx configuration, 
here is couple examples:

http://www.isku.fi/iskuasp/interiorweb.nsf/sp?Open&action=openproduct&lang=fin&id=A47E5D15953F2602C22576340 
need's to go -> http://www.iskuinterior.fi

Okay that was easiest one, because i have these kind of URLS too:

http://www.isku.lt/IskuASP/interiorweb.nsf/sp2?Open&secondNavinf=Eng\Navi\Products\Desks%20and%20tables&secondNavinfa=o&action=openproduct&id=4798A4EB88F4D451C22576690&lang1=eng&P%C3%B6yd%C3%A4t|Ty%C3%B6p%C3%B6yd%C3%A4t|Matrix%20Y 
 should goto:
http://www.iskuinterior.fi/interior/actions/customer_base/product/ProductView.action?productId=210228&returnUrl=http%3A%2F%2Fwww.iskuinterior.fi%3A80%2Finterior%2Factions%2Fisku_interior%2Fproduct%2FProductFamilySearch.action%3FproductFamilyId%3D46275

Problem is that some URLs that i got are escaped like: 
http://www.isku.fi%2FiskuAsp%2Finteriorweb.nsf%2Fsp%3Fopen%26cid%3Dindexfin&ei=p77fS8DxMt2gOMHShfEI&usg=AFQjCNFkPJRA5VvhQ5qs2A1FBU2cH1Y6Fg&sig2=vOXFzYS0xyyqS_iQ2DIIFA
Should goto:
http://www.iskuinterior.fi

Should i just give up and tell customer that its a nogo... My head hurts 
already....
