[squid-users] URL too large??

[Eliezer Croitoru]

Hey Yuri,

It's not right that the Internet is 4*8K in the urls.
It's just that it happens that some of the Internet users abuse their options to enter something in the browser.
Most browsers doesn't support more then 16k and the number which was mentioned was 100K++ so it's either not HTTP or something else.

If you are managing a network like a soho this is a very nice restriction to have 8k or 16k and in some cases 24k limit for a url maximum size.
The defaults are defaults but depends on the applications which are being used the choice of the defaults or special compiled version would change.

It means exactly what it said: URL too long.
In Squid's defaults set 8k for URL size. This was reasonable maximum 10 years ago.
Now it seems too small (at least 4 times) because of now Internet full of adware bullshit (referrals/trackers/counters etc.) which is often more 8k.
You can easy fix it (if you worry about it. It seems for end-user like hang/broken links) if you build squid from source. Just change vaule MAX_URL in src/defines.h and recompile.
But if you do this, beware - some things become slower, and danger of deinal of service exists.
That's it.
WBR, Yuri

I did not dig deep into it I couldn't scan the access log for it because I had no idea what 'too long' meant. 
I will ignore it until someone says they're unable to access a website, and they can give me details of what it is.

I think that the maximum size was 64k and it's way above this. 
It should not be an issue if this is some weird application creating some random url which doesn't have meaning.
But if you know what is creating such a url it's a whole another story.
Can you reproduce\recreate this url?
