Setting sv_downloadurl from the command line - escaping issue

[Shorty06]

I'm trying to set the sv_downloadurl for my server from the command line (rather than server.cfg), but I'm running into a strange issue.

In server.cfg the following will work:
sv_download_url "http://mydomain.com/
However, when I try to set this parameter on the command line when launching srcds:
+sv_download_url "http://mydomain.com"
The // gets treated as comment syntax for some weird reason, and from the server console I see:
sv_downloadurl
"sv_downloadurl" = "http:" ( def. "" )
How can I avoid this happening?

I've already tried the obvious of adding backslash escapes but these don't work.

The reason I want to set this value on the command line is because I'm using Docker and I want to have a generic image with all options specified at runtime.

Try this

+sv_download_url "http:\/\/mydomain.com"

Thanks for the suggestion, but you missed the second last line of my post. Doing that just ends up with URL being set to "http:\/\/mydomain.com" verbatim.
