NimbostratusHTTP HealthCheck monitor with POST Statement
NimbostratusHello Josiah,
We installed wireshark on the node, and captured the requests sent from the F5 monitor and from the server from which we run curl. Here both requests and responses:
Curl Request (as seen from the wireshark capture in the node):
POST /scripts/wpnbr.dll HTTP/1.1 User-Agent: curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.18 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2 Host: 10.10.10.10:8080 Accept: / Content-type: text/xml Content-Length: 169

F5 request (as seen from wireshark capture in the node)
POST /scripts/wpnbr.dll HTTP/1.1 Host: 10.14.44.118:8080 Content-Type: text/xml

As you can see, CURL added some headers that I didn't include (user-agent, content-length, accept). I tried adding content-lenght, and it didn't work. With or without backslahes count.

- The host header is different too. But only your web server logic will tell you why one is good and one is bad (I can't do that). Otherwise you have to try to make them as close to identical as possible.
- Dicky_Moe_13167The forum deleted some tags because it obviuosly took them as html tags, but the xml in both requests is identical. I'll try to make the deaders match.
