How to fix: err_response_headers_multiple_content_disposition error in Google Chrome
To fix the err_response_headers_multiple_content_disposition
error in Google Chrome, follow these steps:
-
Check the server's response headers: This error occurs when the server sends multiple
Content-Disposition
headers in the response. You can use tools like Chrome DevTools to inspect the response headers and identify if this is the case. Open Chrome, navigate to the page causing the error, pressF12
to open DevTools, go to theNetwork
tab, and reload the page. Look at the headers of the request that caused the error. -
Modify server configuration: If multiple
Content-Disposition
headers are present, you need to modify the server-side configuration to ensure that only oneContent-Disposition
header is sent per response. This might involve adjusting settings in your web server (like Apache or Nginx) or your application server. -
Clear browser cache and cookies: Sometimes, clearing your browser's cache and cookies can resolve temporary issues that might lead to this error. Go to Chrome settings by clicking on the three dots in the upper right corner, navigate to
More tools
>Clear browsing data
, select the appropriate time range, checkCookies and other site data
andCached images and files
, then clickClear data
. -
Update Chrome: Ensure that your Chrome browser is up to date, as newer versions might include fixes for known issues. To update, go to
Help
>About Google Chrome
. If an update is available, Chrome will download and install it automatically. -
Disable extensions: Sometimes, browser extensions can interfere with how headers are processed. Try disabling all extensions and see if the error persists. You can manage extensions by going to
chrome://extensions/
. - Contact the website administrator: If none of the above steps resolve the issue, the problem might be on the server side, and you should reach out to the website administrator for assistance.
What are the common causes of the err_response_headers_multiple_content_disposition error in Chrome?
The err_response_headers_multiple_content_disposition
error in Google Chrome is generally caused by issues with the server's response headers. Here are the common causes:
-
Multiple Content-Disposition Headers: The primary cause is the server sending more than one
Content-Disposition
header in the response. This header is used to indicate whether the response body should be displayed inline (e.g., as a web page) or as an attachment (e.g., a downloadable file). Multiple headers can confuse the browser about how to handle the response. -
Misconfigured Server: A misconfigured web server or application server might inadvertently send multiple
Content-Disposition
headers. This could be due to incorrect settings in the server configuration files or due to a bug in the server software. -
Proxy or Load Balancer Interference: If the response goes through a proxy server or load balancer, they might add or modify headers in a way that results in multiple
Content-Disposition
headers. - Server-Side Application Issues: Application-level errors can also lead to sending multiple headers. For instance, a web application might unintentionally add multiple headers due to a programming error or incorrect handling of response objects.
- Browser Extensions: In rare cases, browser extensions might interfere with the processing of headers, leading to this error. This is less common but should be considered if other causes are ruled out.
Can clearing browser cache and cookies resolve the err_response_headers_multiple_content_disposition error?
Clearing the browser cache and cookies might resolve the err_response_headers_multiple_content_disposition
error in certain scenarios. Here's how it can help:
- Temporary Fix: Sometimes, the error might be caused by a corrupted cache or cookies that are leading to incorrect header processing. Clearing these can reset the browser's state and resolve the issue.
- Interference from Cached Data: Cached data or cookies might be influencing the headers sent by the browser, leading to the error. By clearing them, you ensure that fresh data is requested from the server, potentially avoiding the error.
-
Effectiveness: However, clearing cache and cookies is not a definitive solution. If the error is due to server-side issues (like multiple
Content-Disposition
headers being sent), clearing cache and cookies will only provide a temporary workaround. The server needs to be fixed to prevent the error from recurring.
To clear cache and cookies in Chrome, go to the browser settings, select More tools
> Clear browsing data
, choose the appropriate time range, check Cookies and other site data
and Cached images and files
, and then click Clear data
.
Are there any server-side settings that need adjustment to prevent the err_response_headers_multiple_content_disposition error in Chrome?
Yes, there are several server-side settings that you should adjust to prevent the err_response_headers_multiple_content_disposition
error in Chrome. Here are some key adjustments:
-
Ensure Single Content-Disposition Header: The primary fix is to ensure that the server sends only one
Content-Disposition
header per response. This might involve reviewing and modifying your web server configuration, application code, or middleware settings.-
Apache: In Apache, you can use the
Header
directive to set headers. Make sure you're not accidentally adding multipleContent-Disposition
headers. UseHeader set
instead ofHeader add
forContent-Disposition
.Header set Content-Disposition "attachment; filename=\"example.pdf\""
Copy after login Nginx: In Nginx, you can use the
add_header
directive, but ensure that it's not set multiple times for the same header.add_header Content-Disposition 'attachment; filename="example.pdf"';
Copy after login
-
-
Review Application Code: If your application is dynamically setting headers, ensure that it's not inadvertently setting multiple
Content-Disposition
headers. This might involve modifying your application's server-side code to ensure headers are set correctly. -
Proxy or Load Balancer Configuration: If you're using a proxy server or load balancer, review their configurations to ensure they are not modifying the headers in a way that leads to multiple
Content-Disposition
headers. - Debugging Tools: Use server-side logging and debugging tools to monitor the headers being sent. This can help identify where the multiple headers are being added and fix the issue at its source.
By ensuring that only a single Content-Disposition
header is sent in each response, you can prevent the err_response_headers_multiple_content_disposition
error in Chrome.
