    I need to take a list of links that use redirects, follow all redirects and then save the final destination url.

    The query is formatted like:

    <UNIQUE_ID>,<URL_THAT_REDIRECTS>


    I want the output to be formatted like:
    <UNIQUE_ID>,<URL_THAT_REDIRECTS>,<FINAL_DESTINATION_URL>

    Thanks for this. I had to make a couple minor changes but it really helped me out.

    I'm having a bit of trouble getting the final url from some link redirects.

    Here is the preset I am using that includes a few samples that are not working for me:

    The sample urls don't seem to redirect properly in A-parser but when I manually load them in a browser they redirect fine. Anything I could do to improve accuracy?


    Thanks.

    A-Parser processes only 30* redirects. And among those queries that are in the preset, there are links with meta/js redirects. Such redirects are not processed in the scraper.
