Redirect longer than 3972 characters is truncated
I need to redirect user to a url, which is 5000+ characters long.
To do that I set:
set %response.Redirect = url
However, in the browser I receive this header:
LOCATION: <First 3972 characters of the 'url' variable>
In WriteHTTPHeader method of %CSP.Response, where the LOCATION header is
written:
Write "Location: ", <Redirect>,!
After I added a buffer flush, after the above-mentioned line:
Write *-3
Then in browser I received full, correct value of a LOCATION header.
Is there a better solution?
It's a rest API, so maybe there's some callback method I can override to flush the output buffer? Set device mode? Change buffer size?

How about using ServerSideRedirect ?
ServerSideRedirect doesn't work in that context (OAuth authentication) unfortunately.
I also tried setting LOCATION header directly (via SetHeader method) - in that case I get the same truncated output.
Eduard,
I googled around "max url lenght" and found
#1 browser depending
#2 limit yourself to 2048 char.
So is your redirect just URL or URL?urlparams=......
#2 limit yourself to 2048 char.
Nowadays it's fine. Most browsers work with long URLs.
So is your redirect just URL or URL?urplarams=......
It's URL?urplarams=......
One parameter is 5000+ symbols long.
is it persistent across different browsers ?
IF YES -> our problem,
OR do you see different cut off lengths.
I especially distrust IE !
It's on Cache side as adding
Write *-3
fixes the problem.
Congratulations!
docs say:
| Sends any buffered output out the TCP connection; that is, executes a TCP SEND operation on the data in the output buffer. If the data is compressed (/GZIP) stream data, *-3 sends the data without marking the compression endpoint. |
I interpret this:
up to some limit, it is sent somehow automatically
and the eventual rest needs to be pushed out manually or gets never sent or is to late.
??? 
The problem with write *-3 is that it is currently added to a system code. I'm searching for a better solution.
