ArcGIS Server report error 500 if i use URL encoding over REST API

[YongchengChen]

Hi, Guys,

I am using now ArcGIS Server 10.0 as as map server. If i send HTTP request with URL encoding, then i will get 500 error. For example:

The following request works:
GET /ASWeb40/ASC_RIA/loadcard.jsp?http://webdemo-agsn:8399/arcgis/rest/services/Navigation/MapServer/tile/4/2502/3317 HTTP/1.1

And this request doen't work, HTTP response 500
GET%20%2FASWeb40%2FASC_RIA%2Floadcard.jsp%3Fhttp%3A%2F%2Fwebdemo-agsn%3A8399%2Farcgis%2Frest%2Fservices%2FNavigation%2FMapServer%2Ftile%2F4%2F2502%2F3317%20HTTP%2F1.1

Does somebody know how to handle it. It's better to change ArcGIS Server configuration only.

Thanks
