Wrong proxy URL

[domibarton]

Hello there

Amazing plug, thanks a lot.
I tried to use it with my own PlantUML server (remote), and realised it will use the wrong proxy URL:

{server}/plantuml/svg/SoWkIImgAStDuNBAJrBGjLDmpCbCJbMmKiX8pSd9h-1oICrB0Se20000

This URL doesn't work, and returns a 404.
Instead the URL should be (without the plantuml/ path prefix):

{server}/svg/SoWkIImgAStDuNBAJrBGjLDmpCbCJbMmKiX8pSd9h-1oICrB0Se20000

I did a bit of reverse engineering, and found out:

• For the official PlantUML server, there's a plantuml/ path prefix
• For self-hosted (Dockerised) PlantUML servers, there's no plantuml/ path prefix

I'm using the official PlantUML Docker image: plantuml/plantuml-server:v1.2025.7

Is there a config setting to override the path prefix?

@LogeshG5 checked out your code, and I think I could find a rather simple solution to it.
Instead of hard-coding the /plantuml prefix, we could actually remove it, and let the user configure it in the serverurl config.

We just have to update the README.

I'll open a MR for you, since it's just a smaller change.
However, there are always 2 sides of the same coin:

• This change will work for anyone who didn't explicitly configure a serverurl (since we can update the hard-coded default config value)
• However, it will break for users which have explicitly configured a serverurl (since the plantuml/ prefix is no longer implicitly added)

So there are 2 options:

• Keeping that one serverurl option, and updating the code so plantuml/ is no longer implicitly added, and thus forcing users to reconfigure their explicit URL
• Adding a new urlprefix option, which adds a bit of complexity, in favour of not breaking anything?

What do you think is better?
