SERVER_CACHE_INVALIDATE?

Question

Hello,
I am trying to find a way to remove a certain item from the ICM server cache.
I want to use the following function :
<i><b>CL_HTTP_SERVER=>SERVER_CACHE_INVALIDATE( id      = cache_id
                                         type    = 0
                                         scope   = 0 ).</b></i>
but I don't know how to find the cache key.
On this page (
http://help.sap.com/saphelp_webas620/helpdata/EN/38/2d453cf1fcc85ee10000000a11402f/content.htm)
it is explained.
<b>QUOTE :</b>
<i>The URL path is translated, that is, the encoded information about the SAP language and SAP theme, separated by & symbols, is added after the ICF path. This is then followed by another & symbol and the query string with the pseudo query parameters. To restrict the length of this string, a <b>hash process</b> is used on the query string.</i>
I would like to know how this <b>hash process</b> actually works?

I don't think that the processing of the query string described in the help document is not the same thing that is taking place to the URLs in your ICM Cache.  This help refers to the URL mangling that takes place like the following:
kww-d15s.kimball.com/sap(bD1lbiZjPTA4OA==)/bc/bsp/sap ....
Whatever that ending part is, it is appended automatically.  I have some code that forces some content into the cache:
cl_http_server=>server_cache_upload( url      = url
                                       response = cached_response ).
When I look at this in the Cache Monitor I see &en&&A6E90000& appended to the end of the URL.  The &en& is for the language this object is intended for.  I assume that items beginning with the &&& are not lanuage specific. 
However I can also see that if I call the SERVER_CACHE_INVALIDATE method and wildcard the ID parameter with my URL + * it does properly clear my item. I don't know if this helps you out or not.
