Yes! I realized it! In store_id_program, I use the third-party utility "curl -sI http://url.to/real.file.zip"; to define Content-Length and return to squid using the "note" mechanism in the desired ACL for response_delay_pool_access. Similarly, using the "note" mechanism, I force the files, depending on the extension and content in the cache, to use a specific tcp_outgoing_address or the specific FIB. Could not you do this with the help of squid itself? PS: The average user of excellent knowledge of programming languages will not do this, even if they guess how to do it. пт, 22 июн. 2018 г. в 18:22, Alex Rousskov <rousskov@xxxxxxxxxxxxxxxxxxxxxxx>: > > On 06/21/2018 10:34 PM, Michael Pro wrote: > > > I put all the necessary links in the database in step #2. > > I'm quite satisfied with entering this value (Content-Length) after step #3. > > How can I update the data for the link? > > I am not sure I understand the question, but if you are asking how to > add response Content-Length info to some external database, then you > have a few options, including: > > 1.
