Question

User106386122 posted

I created one URL rewrite rule in web config, seems to be working partially. It is not downloading one file completely, gives error in console ERR_CONTENT_LENGTH_MISMATCH with that file's location.

Is there any way I can fix this issue? Please suggest.

Thank you.

Hi kshitij,

According to your description, I couldn't directly find the reason why show this error.

Could you please post the details error message and the rewrite rule?

Besides, I suggest you could post more details about the download file.

If you could post more details information, it will be more easily for us to find the reason.

Best Regards,

Brando

Error is ->  Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

Rewrite rule:

<rule name="ProxyToGo2" stopProcessing="true">
  <match url="olo1/?(.*)" />
  <action type="Rewrite" url="https://someurl.com/{R:1}" />
    
  <serverVariables>
    <set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}"/>
    <set name="HTTP_X_ORIGINAL_HOST" value="{HTTP_HOST}/olo1" />
    <set name="HTTP_ACCEPT_ENCODING" value="" />
  </serverVariables>
</rule>

<outboundRules>
   <rule name="AbsoluteToGo2" patternSyntax="ExactMatch">
      <match filterByTags="None" pattern="https://someurl.com" />

      <action type="Rewrite" value="https://{HTTP_X_ORIGINAL_HOST}" />
   </rule>
</outboundRules>

The above rewrite rule is written in the web.config of https://mydomain.com

So, when I try to navigate to https://mydomain.com/olo1/web/583

It just shows few things of the page with the error "Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH" in the console.
