[users@httpd] Apache does not post data correctly to tomcat

[<hemanth.velluri@xxxxxxxxx>]

Hello,

 

OS: RHEL 4.0

Apache version: httpd-2.0.52-12.ent

Tomcat version : 5.5.9

 

     In our scenario, all the requests are posted to apache web server and then apache forwards these requests to tomcat server through mod_jk connector. The request body is of XML type. When the request size is less than 8808, then request is processed correctly and if it exceeds 8808 bytes, then the request is appended with old chuncks of the request. Where I get parse exceptions since I am parsing the requests.

 

For e.g : <example>

                       <example1 a=”b”/>

                       <example2 c=”d”/>

             </example>

 

This occurs as:

 

            <example>

                       <example1 a=”b”/>ple1 a=”b”/>

                        <example2 c=”d”/>

             </example>

 

Note: I posted directly to tomcat server, where it is accepting large size of requests and processing correctly.

 

In the httpd.conf, I used the directives like LimitRequestBody to 2147483647 (i.e., 2 GB) and tried with 0 option also to accept unlimited data. And similarly,

 

LimitXMLRequestBody with size values 1000000 and 2147483647. But the apache is sending malicious data.

 

 

I am reading the request in my servlet code as:

 

           BufferedReader buffReader = req.getReader();

           

            requestXml = new StringBuffer();

           

            String s = null;

           

            while ((s = buffReader.readLine()) != null) {

                        requestXml.append(s);

            }

            buffReader.close();           

                                

            fileContent = requestXml.toString().trim();

 

Could anyone tell me that, are there any other directives to be set to solve this issue?

 

Regards,

Hemanth
