javascript - Intermittent failure to load images - ERR_CONTENT_LENGTH_MISMATCH -


the problem

my website fails load random images @ random times. intermittent failure load image following error in console:

"get example.com/image.jpg net::err_content_length_mismatch"

image either doesn't load @ , gives broken image icon alt tag, or loads halfway , rest corrupted (e.g. colors screwed or half image greyed out).

setup

litespeed server, php/mysql website, html, css, javascript, , jquery.

important notes

  • problem occurs on major web browsers - intermittently , various images.
  • i forcing utf-8 encoding , https on pages via htaccess.
  • hosting provider states permissions set correctly.
  • in access log, when image fails load, gives '200 ok' response image , lists bytes transferred '0' (zero).
  • it images fail load maybe 5% of time css file or javascript file.
  • problem occurred after moving servers apache litespeed , has been persistent on several weeks.
  • gzip , caching enabled.

this error definite mismatch between data advertised in http headers , data transferred on wire.

it come following:

  1. server : if server has bug modules changes content don't update content-length in header or doesn't work properly.
  2. proxy : proxy between , server modifying request , not update content-length header.

this happens if setting wrong content-type.

as far know, haven't see problem in iis/apache/tomcat custom written code. (writing image on response stream)

it caused ad blocker.

try disable or adding exception domain images come from.
