[jira] [Commented] (TS-3656) Activating follow redirection in send server response hook does not work for post

["Sudheer Vinukonda (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-3656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14615707#comment-14615707 ] 

Sudheer Vinukonda commented on TS-3656:
---------------------------------------

Should this change be reverted from 6.0.x/master as it seems that it's breaking (causing issues on) normal POSTs? 

Fwiw, as I mentioned already, supporting redirect follow for POSTs requires a lot of more analysis than the changes here.

> If you have a plugin on the TS_HTTP_SEND_RESPONSE_HDR_HOOK, calls TSHttpTxnFollowRedirect(txn, 1), redirecting a POST request will fail.
> In the not so bad case, the POST request will be redirected to the new location, but the POST data will be lost.
> In the more bad case, ATS will crash.
> The issue is that the post_redirect buffers are freed early on.  One could delay the post_redirect deallocation until later in the transaction.
