- Maria from Bioversity recommended that we use the phrase "AGROVOC subject" instead of "Subject" in Listings and Reports
|
||||
- I made a pull request to update this and merged it to the `5_x-prod` branch ([#418](https://github.com/ilri/DSpace/pull/418))

## 2019-04-07
|
||||
|
||||
- Looking into the impact of harvesters like `45.5.184.72`, I see in Solr that this user is not categorized as a bot so it definitely impacts the usage stats by some tens of thousands *per day*
|
||||
- Last week CTA switched their frontend code to use HEAD requests instead of GET requests for PDF bitstreams
|
||||
- I am trying to see if these are registered as downloads in Solr or not
|
||||
- I see 96,925 downloads from their AWS gateway IPs in 2019-03:

- And from the server side, the nginx logs show:
|
||||
|
||||
```
|
||||
78.x.x.x - - [07/Apr/2019:01:38:35 -0700] "GET /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 68078 "-" "HTTPie/1.0.2"
|

78.x.x.x - - [07/Apr/2019:01:39:01 -0700] "HEAD /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 0 "-" "HTTPie/1.0.2"
|
||||
```
|
||||
|
||||
- So definitely the *size* of the transfer is more efficient with a HEAD, but I need to wait to see if these requests show up in Solr
