Topic: Redirect and doing special things

[ThomasT]

Hi,

although I often used (means devolped something that run in it) apache-webserver I don't have a clue.

I think I descripe what I want to do and hope for tipps.

We want to install a proxy that gets https-request, e.g. for an image. But this request contains a special UUID.

https://myserver/niceimage.jpg?UUID=42

the proxy shall extract (and remove) the uuid and redirect (302) to the actual server providing the requested resources (e.g. https://otherserver/niceimage.jpg).
The uuid shall be written to file or to database or whatever.

The server should be able to process and aswers requests "get all UUIDs you got until now" from outside.

My question how to do this in the most effective way?
I hope its clear what I want. If not, please ask

Regards Thomas

Hello Thomas,

I would use mod_rewrite on myserver to get all requests containing the UUID rewritten to a php-page (of perl or whatever you prefer).
This php-page writes the UUID to the database (including a check if the UUID is alread there) or simply append it to a plain-text-file (which can be processed with the linux-tools sort + uniq "cat uuid.txt | sort | uniq") for analysis. And it redirects the user to the new URL.

The "how-to-rewrite-only-requests-with-defined-parameters" can be found here: https://stackoverflow.com/questions/4703476/what-rewriterule-would-be-to-redirect-based-on-the-on-query-string-parameters

There might be other ways containing more magic but I think this is an easy-to-understand-approach - today when implementing it and in some months/years when looking at it and thinking "how did this work?"

Hope this helps?

Best regards
Matthias

I'll try it. Thanks.

Note that Apache 2.4 can do that even without complex rewrite rules

See https://mariobrandt.de/archives/apache/apache-2-4-disallow-access-to-a-certain-location-if-a-query-string-is-set-952/
