3. The problem I’m having:
I am programmatically adding reverse_proxies to the json and sending the whole file using the load end-point.
What I am seeing, is if the command is repeated, then instead of 4 proxies being added, it befomes 8. The next time it is 12. It’s as if Caddy is merging what I send, instead of starting “fresh”.
If I sent the default json, with no added proxies, then the currently added proxies remain.
4. Error messages and/or full log output:
if I run this after a reset I can see the proxies remain:
curl localhost:2019/config/ | grep dcam-dev
5. What I already tried:
I have tried playing around with caching to see if that changes anything, but none work:
‘Cache-Control’: ‘must-revalidate’
‘Cache-Control’: ‘no-store’
‘Cache-Control’: ‘no-cache’
What this do tho, was force caddy into not thinking the cache had changed.
Before adding ‘Cache-Control’ command, I was getting this:
Aug 21 09:26:16 FLEX-5 caddy[1037]: {"level":"info","ts":1598023576.419586,"logger":"admin.api","msg":"received request","method":"POST","host":"localhost:2019","uri":"/load","remote_addr":"127.0.0.1:54164","headers":{"Accept":["application/json, text/plain, */*"],"Connection":["close"],"Content-Length":["9050"],"Content-Type":["application/json"],"User-Agent":["axios/0.19.2"]}}

Aug 21 09:26:16 FLEX-5 caddy[1037]: {"level":"info","ts":1598023576.4207559,"logger":"admin.api","msg":"load complete"}
But with the cache command, I now get this:

But, the contents of Caddy are unchanged when I do this:
curl localhost:2019/config/ | grep dcam-dev
or, the data is merged in some way (unexpected)
After adjusting our default caddy json file, I send it with axios like this:
function putConfig (config) {
return new Promise((resolve, reject) => {
axios({
method: 'post',
url: 'http://localhost:2019/load',
headers: {
'Content-Type': 'application/json',
'Cache-Control': 'must-revalidate'
},
data: config
})
.then(results => {
console.log(results)
resolve(results.data)
})
.catch(error => {
console.log(error)
reject(error.message)
})
})
}
response back is 200
