F5 ASM | Bot Defense | TSPD JavaScript errors

Hi everyone! 

I have an open case at F5 and I got a response that I don't like at all. The case was opened because after activating Bot Defense for a website we started to have several errors in the browser console. These errors all come from the TSPD JavaScript.

The F5 support give me this response: "...caused by the bot profile to test the different browser capabilities"


Does anyone who uses bot defense have the same symptom?


p.s - If i turn off bot defense the errors disappear.

  • Seems there are network errors and the injected JavaScript can not fetch resources. Uris starting with /TSPD/ and /TSbd/ must be reachable and ASM must be enabled for this uris. They are handled by ASM. Check the network tab to check if the requested uris are correct.

  • It's not correct, the JavaScript is trying to access to
