Piping Server - Quick Reference

• Path prefix: All transfers must use /p/ (e.g., /p/mypath)

• One-time only: Each message can be received only once

How to send

Send a file:

curl -T myfile.txt https://example.com/p/mypath

Send text:

echo "Hello!" | curl -T - https://example.com/p/mypath

Send compressed:

cat file.txt | gzip | curl -T - https://example.com/p/mypath

Save to file:

curl https://example.com/p/mypath > received.txt

Receive compressed:

curl https://example.com/p/mypath | gunzip > file.txt

Set waiting timeout (seconds):
```
curl -H "X-Timeout: 30" -T myfile.txt https://example.com/p/mypath
```
Sender disconnects if no receiver connects within timeout.

Enable manual cancellation:

curl -H "X-Cancel-Key: mysecret" -T myfile.txt https://example.com/p/mypath

Then cancel with:

curl -X DELETE -H "X-Cancel-Key: mysecret" https://example.com/p/mypath

Check if channel exists:
```
curl -I https://example.com/p/mypath
```
Returns 200 if channel exists, 404 otherwise. Does not consume the channel.
