[TC-546] error_url required in the url_sig file

[limited]

The error_url parameter in the URL signature file is required, if not present trafficserver doesn't start.

Seems like TO handles generating the proper location of for the url_sig in the the database to all servers assigned, although the error_url is not.

• I tried to put the parameter in the DS profile parameter, but it didn't get generated on disk.
• Thinking that a default of `error_url = 403` should be dynamic generated if not present to prevent trafficserver from starting. This could have other implication.
• Other suggestions?

Is there and ETA or release number which will have a fix for that issue. I have run lately into the same problem. Seems even the new golang code is not appending that line into the database or the local file which will be pushed onto the servers.

Think a good approach would be

• to give an Option via ATC GUI to assign a customised line into the file/database
• amend the url_sig plugin with a default operation if the line is not present error_url = 403
