[...] no_content_length error messages (for each episode that has a /podlove/file/tracking URL) [...]

[...] server is not supplying the Content-Length: header. Are you generating download files on the fly? :)

It's a webhosting service, so I'm not sure I can influence what it sends or generates. However, there is definitely a length parameter in each file's <enclosure /> (with Podlove Tracking switched on). Can Bitlove be made to fall back to that one?

Bitlove compares both values to check for updated files. Not delivering a Content-Length header for static files is configuration bug in the server infrastructure.

Absence of this header for static files is strange indeed. Do you support Range: requests at all? It won't work without.

According to two header checking tools, my webhoster does serve the Content-Length and Accept-Ranges: bytes if the file's URL is used, for example: http://www.konscience.de/wp-content/uploads/kns025-flucht-nach-vorn-in-die-botanik.m4a Same result using the ?ptm_ parameters; as expected, I guess.

For the Podlove Tracking URL of the same file however, the 301 redirect is accompanied by Content-Length: 0 by the 1st tool, while the 2nd one reports only HTTP/1.1 200 OK and Content-Type => text/html; charset=UTF-8. Example: http://www.konscience.de/podlove/file/1693/s/download/c/buttonlist/kns025-flucht-nach-vorn-in-die-botanik.m4a

If I set up a 301 redirect in Podlove's Expert Settings manually from one audio file's direct URL to another, the correct headers are also sent.

I don't know, but it looks to me as if:

In any case, I'm sure now it isn't a Bitlove issue, except for the feature request idea of the fall-back ;-) Shall we move the problem part of this issue to Podloves's tracker?

Everything has been looking fine to me, except for the link to kns006.

Wrong redirect; fixed now. Thank you!
