I am having web page make ajax HTTP PATCH call to the same domain restful service. It failed ONLY for mobile phone for chrome browser, like the below

$.ajax({
url : "same-domain/path",
data : "{}",
type : 'PATCH',
headers: {
    "Cache-Control":"no-transform",
    "Content-Type":"application/json"
},
processData: false
}); // failed ONLY if any payload presented

Status Code:502 Bad Gateway

This page cannot be loaded via the Chrome Data Compression Proxy. Try reloading the page.

This is quite annoying since all we tested desktop browsers and mobile NOT-chrome can do PATCH successfully. Actually, mobile chrome does succeed ONLY if no any payload

$.ajax({
url : "same-domain/path",
data : "",
type : 'PATCH',
headers: {
    "Cache-Control":"no-transform",
    "Content-Type":"application/json"
},
processData: false
}); // is OK ONLY if no payload at all

K. thanks for some related discussion here so i know the cause. I wish this can fix this and respect cache-control header. And meanwhile, what is your way to walkaround?

I am the tech lead for the Chrome compression proxy. Can you share more details such as the URL used? PATCH should be supported by the proxy so I am surprised you are seeing this issue.

  • Is there a way to disable proxy for certain requests? Like for a captcha image? As captcha content is saved in SESSION, but the session is valid only between proxy->server, and not on the enduser->server route. – Pentium10 Mar 27 '15 at 19:07
