Context.Request.RawUrl returns an invalid partially encoded URL, how can I fix it?

Question

Since I decided to pass the identifier of a specific record along the query line, so that I encrypt the identifier ( id=090ed4fe-daec-452d-b025-f664dcc1164d) and bind it to the URL.

As we all know, URL-encoded value for / is% 2f. Thus, on a specific application instance, the id ( id=090ed4fe-daec-452d-b025-f664dcc1164d) value , which was encrypted and then encoded, returns the value:

M2vaIbPkOqO6lw4jv%2bqE2f%2fhTrK495ny92uPcLBOJBNcMpg1RUme%2fvAo6LyKfdp9e

When I follow the link, I get:

M2vaIbPkOqO6lw4jv+qE//hTrK495ny92uPcLBOJBNcMpg1RUme/vAo6LyKfdp9e

for the "encrypted and encoded" part, which is correct. But when I use the property Context.Request.RawUrlto get the url, I get:

M2vaIbPkOqO6lw4jv+qE/hTrK495ny92uPcLBOJBNcMpg1RUme/vAo6LyKfdp9e

, , (1) '/' , , .

, , . , (2) '/' (2f% 2f), .

, Context.Request.RawUrl (1) '/'?
