URL truncated with 255 characters

I have a JavaScript widget that interacts with my Rails application by creating tags in the DOM. From time to time, I see an invalid request in my server logs, where the URL is truncated with 255 characters:

http://myapplication.example/mycontroller/1/myaction?hostname=www.mycustomer.example&request[param_a]=3&request[param_b]=1&request[param_c]=0&request[param_d]=0&request[param_e]=3&request[param_f]=1&request[param_g]=4&request[param_h]=0&request[param_i]=5&request

From Google and Stackoverflow ( What is the maximum URL length in different browsers? ), It seems that 255 characters are not a valid limit for URLs.

Here is what I know:

  • This is a sporadic problem, this does not happen in all queries
  • URL truncated at 255 characters when this happens
  • When this error occurs, the user agent is not written to backtrace

Here is what I DO NOT know:

  • In what types of browsers does this error occur? Maybe some kind of mobile browser ...

What is the best way to cause this problem?
