    Litespeed generated 500 errors on POST

    "There should be request headers logged without " In the same debug file? If I can't search the log on IP, I'm not sure I would be able to locate the entries due to the volume of requests logged.

    Litespeed generated 500 errors on POST

    Thanks for the reply. No it's not HTTPS unfortunately. I did tweak the debug settings for maximum, here is the output: error.log.2021_09_12.02:2021-09-12 11:13:53.997484 [DEBUG] [26061] [T0] [XXX.XXX.XXX.XXX:43388] Headers: POST /callback/635c2f643c425960356b08dc25cb0ff8 HTTP/1.1...

    Litespeed generated 500 errors on POST

    Hi, We've been using Litespeed for many years without any problems but a couple of days started getting some 500 errors come up that we can't reproduce. Using LS 6.0.8 but also happened in 6.0.5. Debug log: 2021-09-11 16:01:23.738460 [DEBUG] [29960] [T0] [XXX.XXX.XXX.XXX:13498#ServerV2] use...

    [Resolved] DDoS - long requests

    Hi, Sorry to bring up this old thread but we've recently disabled CloudFlare and now we have exactly the same problem as before. Is there a way (maybe something has changed in the last 2 years!) to block a POST request to a certain URL before the POST request has finished? At the moment it...

    Failed to parse IP address [unknown] in X-Forwarded-for header

    Yes - I think now it is to do with IP v6 and probably not related to LiteSpeed. Thanks.

    Even though we are now blocking all the IPs in LiteSpeed that request the URL, the request queue is still full of: 85.154.38.180RB634.2276338/7007026589/6589V2-"POST /Uxi6h HTTP/1.1" 212.126.103.1460RB361.3731366/73748320/20V2-"POST /Uxi6h HTTP/1.1"...

    [Resolved] DDoS - long requests

    Client IP in Header - for different websites?

    Hi, I need to use the feature 'Client IP in Header' but only for certain virtual hosts. Is this possible or is it a global only thing? If it's not possible, is there a way I can add a custom header so the real IP of the user is put in X-Forwarded-For if it doesn't exist? The problem...

    Connection reset by peer

    Thanks - I've seen random blank pages but didn't realise this is the problem. Never the same script every time. I'll enable core dump for PHP - where would this be stored?
