Search with Special Characters : 502 Server Error ?

I’ve been a bit busy lately with work and Weekend Testing, Learning new concepts and trying to learn more. Hence the lack of updates on my blog. 

Recently, I had a conversation with testers on twitter:

Searching with Special characters shows 502 error is it fine ? #testingerrors

@srinivasskc That's Bad Gateway (#502). It is not fine and it needs to be handled by server side to avoid that message to be shown to user.

@srinivasskc You should also investigate the logs at server side if possible. It can reveal, that problem is worse than just stupid err msg

@teemuvesala How can we check the logs at server side?

@srinivasskc Ask from sysadmin if you can get access to error log. Send the special chars, see the last lines investigate what errors are.

Thanks  to Santhosh Tuppad and Teemu Vesala...for sharing your thoughts.

I wanted this conversation as-is because, it can help others and me - whenever i find these kind of errors.

Happy Thanksgiving day to all my blog followers...
