Apache 1.3.37 server returnes 403 Access Denied when post request

Question

update 2022-05-14

i found that server shows 403 when post request, not get request. get reqeust works well, not post.

---

hi i got problem with the apache server

that server started response 403 Access Denied in unexpectedly when users access some files. that files was working well before it. and other files in same directory can access well.

detailed error message is " You don't have permission to access "{FILE_PATH}/cart_write_exec.php" on this server."

i try to fix it with bunch of stackoverflow pages:

Directory Indexes: Error message "Forbidden You don't have permission to access / on this server"

cart_write_exec.php is specific php file. not directory. so i think it is useless

deny,allow directives: Error message "Forbidden You don't have permission to access / on this server"

that server's httpd.conf is already seted. and i didn't any modify to that file since 2012.

<Directory /home/*>
    AllowOverride All
    Options +ExecCGI
    Order allow,deny
    Allow from all
</Directory>

Require directive (Apache 2.4): Error message "Forbidden You don't have permission to access / on this server"

that server's apache version is 1.3.37

Files permissions: Error message "Forbidden You don't have permission to access / on this server"

cart_write_exec.php is already 777 and directory contained that file is 777 too.

SELinux security context: https://www.happyjung.com/lecture/2481

i think selinux security context is not installed on my server.

cuz ls -alZ is shows nothing like below.

but i try do the chcon --type=httpd_sys_content_t cart_write_exec.php. it returns error: chcon: can't apply partial context to unlabeled file cart_write_exec.php

that server's apache version is 1.3.37, php version is 4.4.7, centos version is centos-release-5-1.0.el5.centos.1... whatever..
