Uri and the %2f and %5c escape codes.

Paul Linville

4/20/2008 5:41:00 PM

We need to be able to use the following URL that is given to us by a test
harness.

hTTps://000.000.000.000:000/59B9F4F20E2911DDA2C7E519FDF7B25D;59B9F4F30E2911DDA2C79DE1971E1E45/@%5C%A1%38jzrF%88K6czQq%2A~%bc%e0HMn%027Cxh:Kc)R+z%0EAPySaroF%19b-0X2G%06F)%3du%c2%55eOQY%03DZd*:8cviSj.A~CYRe.H.$%4CMp%CBCr'xm!y%D3HW%F2%5D+7@JvR%B7Z


I cannot construct a Uri and use that Uri in a web request. I always get 404
not found. One thing I noticed is that the %5C is converted to a forward
slash ("/") and I don't think it is supposed to be with respect to what the
server is expecting.

Others have passed the harness and have been able to use the above URL but I
don't know what platform they are using.

I am pretty sure it has to do with the %5c. Another URL that fails has the
%2f escape sequence in the path. From what I understand the Uri class ALWAYS
unescapes those two to conform with rfc 3986.

If I understand everything correctly the escape codes %5c and %2f cannot be
used in the path segment when using the Uri class. They can be used in the
query segment, however.

First, can somebody confirm my suspicions?

Secondly, does anybody know how I can work around this?

I would try adding a question mark right after the slash next the port.

so : https://IP:PORT/?....

Ah, but WHICH kind of infinity? Aleph-null, Aleph-one, or something else?

Who knew that there were an infinite number of angels? There's not an
infinite number of gods, nor sons of god, nor Satans nor grains of
sand in the ocean, yet there are an infinite number of angels.

Hmm. Is there a corresponding infinite number of demons?


He didn't say how many /were/ dancing, he said /may/ dance.

Point of interest... As angels are spiritual beings existing in a spiritual
realm, there are no pins for them to dance on in the first place.

Seems to be intellect. It's a question of room, not availability.
